Jenny ran 5 more miles this week than she ran last week. Let t be the number of miles she ran last week. Write an expression that tells how many miles she ran this week.
Answers
Answer:
t+5+x
Step-by-step explanation:
It says Jenny ran 5 more miles than last week so you find the number from last week then add 5. X is the miles she ran this week
Answer:
t + 5
Step-by-step explanation:
In this problem, you have to recognize what the information is telling you in terms of the vocabulary used. For example, the first sentence tells us that she ran 5 more miles than last week. This is key because it lets us know that our expression will have an addition sign.
Once you recognize that the problem is telling you to add 5 to her previous distance, you get a final expression of t + 5. Hope this helps!

Find two posiitive even consecutive integers such that the square of the smaller integer is 10 more than the larger integer.
Answers
Answer:
The two numbers are 4 and 6
Step-by-step explanation:
Suppose we have:
x=The smallest even integer
x+2=Next even integer
Recall even numbers occur every other integer.
The condition of the problem states the square of the smaller integer is 10 more than the longer integer:
[tex]x^2=10+x+2[/tex]
Rearranging and simplifying:
[tex]x^2-x-12=0[/tex]
Factoring:
[tex](x-4)(x+3)=0[/tex]
We have two solutions:
x=4, x=-3
Since the integers must be positive:
x=4
Next even integer= x+2=6
The two numbers are 4 and 6

What is the Equation of a line that has a slope
of -3 passes to the point (4,-5)
Answers
Answer:
y= -3x + 7:)
Step-by-step explanation:
Hope this helps!
Answer:
y = - 3x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 3 , thus
y = - 3x + c ← is the partial equation
To find c substitute (4, - 5) into the partial equation
- 5 = - 12 + c ⇒ c = - 5 + 12 = 7
y = - 3x + 7 ← equation of line
The sum of two consecutive numbers is 63. Find the two numbers.
Answers
Answer:
the two numbers are 31 and 32.
Step-by-step explanation:
x+(x+1)=63
2x+1=63
2x=62
x=31
The answers are 31 and 32
The sum of two consecutive numbers is 63. Consecutive numbers are numbers that are in a row (e.g. 1, 2, and 3 are consecutive integers). This means we can represent the two consecutive numbers with x and x+1. Plugging the numbers back into the equation, you get
x + x+1 = 63
Simpifying, you get
2x+1 = 63
Now, you just need to isolate x. To do this, you should subtract 1 from both sides, making the equation.
2x=62
Lastly, you need to divide both sides by 2, making making the equation
x=31
The two integers are x and x+1, and when you plug 31 into that, the numbers are 31 and 32.

How do you know what 0 to place the decimal point at for scientific notation? Please explain in detail.

To convert a decimal into scientific notation, move the decimal point until you get to the left of the first non-zero integer. The number of places the decimal point moves is the power of the exponent, because each movement represents a "power of 10".
Given the formula y = -1/2x - 4, what is the slope and y-intercept of the graph? PLEASE HELP!
Answers
Answer:
the slope is -1/2 and the y-intercept is -4
Step-by-step explanation:
The original formula is y=mx+b. m is the slope of the graph and b is the y-intercept. You just plug in the numbers to the original formula to get the formula for the graph. The slope is always the number that is right next to the x, or the number which is multiplied by the x. The y-intercept is always the number that is not by x.

O {(1, -7), (2, – 8), (-2, 7), (1, 8)}
Answers
Answer:
B
Step-by-step explanation:
For a relation to be a function, it must fit the following criteria:
Each input must be matched to exactly one output. Inputs cannot repeat*. Outputs can. *If inputs do repeat, they must be equal the same output as the other inputs.So, let’s go through each of the choices.
Choice A)
In this relation, -7 repeats. It simultaneously equals -1 and -8. So, this is not a function since it’s repeating and it doesn’t equal to same.
Choice B)
In this relation, none of the inputs are repeating. Therefore, B is the corrrect answer.
Choice C)
In this relation, -2 repeats four times. And each time, it equals something different. Therefore, C is not a function.
Choice D)
Here, 1 repeats twice, equalling both -7 and 8. Since it appeared more than once and is not equal to the same thing, D is not a function.
Therefore, our answer is B.

Add both lengths and you see the overlap thats 12 cm so subtract that to get the length.
Answer:
1.94 m
Step-by-step explanation:
1 meter=100cm
Then we need to convert the two lengths which is 135 cm and 83 cm
so then since it is overlap we multiply by two 12 cm*2= 24 cm
Then we add 135 and 83= 135+83 = 218 cm
218 cm - 24 cm = 194 cm
So then 194 cm to m = 1.94 m
