Solve for x:
3x + 2 = 7x - 6
Answer:
[tex]\sf D.\;\;x=2[/tex]
Step-by-step explanation:
[tex]\sf 3x + 2 = 7x - 6[/tex]
Subtract 2 from both sides:-
[tex]\sf 3x+2-2=7x-6-2[/tex]
Simplify:-
[tex]\sf 3x=7x-8[/tex]
Subtract 7x from both sides:-
[tex]\sf 3x-7x=7x-8-7x[/tex]
Simplify:-
[tex]\sf -4x=-8[/tex]
Divide both sides by -4:-
[tex]\sf \dfrac{-4x}{-4}=\dfrac{-8}{-4}[/tex]
Simplify:-
[tex]\sf x=2[/tex]

599 cm2
217 cm2
307 cm2
689 cm2
Answer:
11. 3,396
Step-by-step explanation:
Given:
Circumference of Mars = 10,664 km
Determine the diameter of Mars.
D = 2r
C=2πr
Solution:
Since we do not have the value of r, we will solve for r in terms of C.
C=2πr
10,644 = 2πr
r = 10644/ 2π
r = 1694.04 km
Now that we know the value of r, we can solve for d.
D = 2r
D = 2( 1694.04km)
D = 3,388.09 km
The nearest value is 3,396 km on the choices, but the answer rounded to the nearest km is 3,388 km

Round the number. Write the result as a product of a single digit and a power of 10.
0.00001726
Answer:
= 1.726 × 10^-5
= 2 x 10^-5
Step-by-step explanation:
Move the decimal to the right. Moving to the right makes the exponent a negative number. Round 1.726 to the nearest whole number as 2.
What is the mode of this data set?

Help please!!!! finding the mean/mean absolute value(MAD)
PLease and thank you!!!!
94,86,95,99,88,90
A. mean is 92
B. mean absolute deviation is 4
C. values differ from the mean by an average of 4
A.
94+86+95+99+88+90=552
552 divided by 6 = 92
mean = 92
C.
94-92=2
92-86=6
95-92=3
99-92=7
92-88=4
92-90=2
2+6+3+7+4+2=24
24 divided by 6 = 4

Answer: 4/50 equals 2/25
Step-by-step explanation:4/50 and 2/25 equal.08. To get it I did 2×2=4 and 25×2=50 to get 4/50 which equals 2/25 or .08
Answer:
.08 or 8/100
Step-by-step explanation:
First I'd change the fraction to an equivalent fraction with 100 as the denominator since we want the number in hundredths.
If you multiply 25 by 4 you get 100, so that would be the denominator.
Since you multiplied the denominator by 4 you'd also have to multiply the numerator, 2. 2 times 4 is 8.
Now your fraction is 8/100, and if you change this into decimal form, you get .08
A set of tiles, one of each of the 26 letters of the alphabet, are placed in a container. What is the probability of choosing first a vowel and then a consonant without replacing the first tile?
I need your help with this haha
Answer:
(4, 8) also known as option B. is the correct answer.
remember
x comes first
y comes second
and
x goes across
y goes up and down
Answer: the answer is ( 4, 8) which is the second choice .
Step-by-step explanation: the 4 is on the x axis line and the 8 is on the y axis line . So coordinates 4,8 represent E on the coordinateplane . HOPE IT HELPS YOU .PLEASE GIVE BRAINLIEST .THANKS .
Which term best describes the graph of y = x – 1?
1)increasing
2)decreasing
3)constant
4)positive
Answer:
mark brainliest please!!! <33
Step-by-step explanation:
Since the slope is a positive slope, hence the term that best describes the graph of y = x – 1 is increasing
The standard equation of a line in slope-intercept form is expressed as:
y = mx + b
where:
m is the slope of the lineb is the y-intercept of the lineThe nature of the graph is determined by the slope value.
If the slope is positive, the graph is increasing while if the slope is negative, the graph is decreasing.
Given the function y = x - 1, compared with the general equation;
mx = 1x
m = 1
Since the slope is a positive slope, hence the term that best describes the graph of y = x – 1 is increasing

The table shows the change in the water level (in centimeters) of a reservoir for three months. Find the total change in the water level for the three-month period. Write your answer as a fraction or mixed number in simplest form.
The total change in the water level for the three-month period is (BLANK) centimeters.
Answer:
The total change in the water level is [tex]-\frac{33}{28}[/tex]
Step-by-step explanation:
In order to get the total change in something is to add all the numbers together. So, over that three month period, you add -1 3/4-1/28-15/28. SInce you are adding fractions, it helps to have all the denominators the same. Change -1 3/4 into -49/28. (all I did was turn the fraction into an improper fraction then did [tex]\frac{7*7}{7*4}=\frac{49}{28}[/tex] )
Now that we have all the same denominators, just add them/combine them.
[tex]-\frac{49}{28} -\frac{1}{28} -\frac{15}{28}[/tex] = [tex]-\frac{33}{28}[/tex]
Hi can somebody help me solve this?
X+2.6=10.4
Answer:
[tex]x + 2.6 = 10.4 \\ x = 10.4 - 2.6 \\ x = 7.8[/tex]
Answer:
x = 7.8
Step-by-step explanation:
x + 2.6 = 10.4
- 2.6 -2.6
-------------------
x = 7.8
The area of a triangular block is 81 square inches. If the base of the triangle is twice the height, how long are the base and the height of the triangle?

Step-by-step explanation:
Simplify the expression. Write your answer using decimals.
Answer:
2.4h+2.2
Step-by-step explanation:
4.5h-7.7+9.9-2.1h
To solve this problem, we need to combine like terms.
Because 2.1h is negative, we can subtract it from 4.5h and get 2.4h.
2.4h-7.7+9.9.
We can do the same thing with -7.7 and 9.9. 9.9-7.7=2.2. We have to stop there because constants, numbers without variables, can't be added or subtracted to coefficients, numbers with variables.
Therefore, the simplified equation is 2.4h+2.2.
1 Look at the following rules for two number patterns. Both patterns start with 40.
Pattern P: "Subtract 2"
Pattern Q: "Subtract 6"
Which statement is true about the corresponding terms in the two patterns?
a
Excluding the first term, a term in Pattern P is always 4 greater than its corresponding term in Pattern Q.
b
Excluding the first term, a term in Pattern Q is always 6 greater than its corresponding term in Pattern P.
c
Starting with 0, the difference between the corresponding terms in the two patterns decreases by 2.
d
Starting with 0, the difference between the corresponding terms in the two patterns increases by 4.
2 The following rules for two patterns are shown:
Pattern A: "Start at 100, subtract 10"
Pattern B: "Start at 75, subtract 5"
Which term in both the patterns has the same value?
a
Term 4
b
Term 5
c
Term 6
d

Answer:
option B
Step-by-step explanation:
we first subtract 4 by both sides to get:
3x < -15
now we just divide by 3 on both sides to get
x < -5
the answer is B
Answer:
see below
Step-by-step explanation:
3x+4 less than or equal to -11
Subtract 4 to get 3x isolated
3x < -15
Because x still has something attached to it, you divide by 3
x is less than or equal to -5
Calculate the volume of the following figure.
19 units3
20 units3
24 units3
22 units3
Answer:
24
Step-by-step explanation:

Answer:
[tex]\boxed{\sf{24\ units\ ^3}}[/tex]Step-by-step explanation:
In order to solve this, you must use the volume of the cube.
[tex]\underline{\textbf{VOLUME OF THE CUBE FORMULA:}}[/tex]
[tex]\Longrightarrow: \sf{V=L*W*H}[/tex]
L: (length) = 3W: (width) = 2H: (height) = 4Multiply.
Use the order of operations.
PEMDAS stands for:
ParenthesesExponentsMultiplyDivideAddSubtract[tex]\Longrightarrow: \sf{3*2*4}[/tex]
First, do multiply.
[tex]\Rightarrow: \sf{3*2=6}\\\\\\\Rightarrow: \sf{6*4=\boxed{\sf{24}}[/tex]
Therefore, the volume of the cube is 24 units³, which is our answer.I hope this helps. Let me know if you have any questions.
