!!will give brainliest!! If you want addition to be done before multiplication, what do you need to add to the problem?
I beive your doing "Order of Operations"
Heres some information.
Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction. Continue to preform multiplication and division from left to right. Next, add and subtract from left to right.

Write the equation of the line that passes through each pair of point (1,2) (-1,-3)
Answer: y = 3
Step-by-step explanation:
So, we must find an equation of a line that passes through these two points such that we find the slope first as,
m = (3-3) / (2-(-1)) = 0 / 3 = 0. Then we bring up the point-slope form of an equation to find the line such that
y - y1 = m(x - x1). Next,
y - 3 = 0(x - (-1))
y - 3 = 0..............Then add 3 such that the equation of a line is

Suppose that a phone that originally sold for $800 loses 3/5 of its value each year after it is released.
After 2 years, how much is the phone worth?
Write an equation for the value of the phone, , years after it is released.
Answer:
It will be worth $128.
Step-by-step explanation:
After 1 year, 3/5 of 800 is 480 which leaves the value at $320, and then after 2 years, 3/5 of 320 is 192. 320-192 leaves the value at $128.

1. The scale of a map is 1:1000. What are the actual dimensions of a
rectangle which appears as 4 cm by 3 cm on the map? What is the area
on the map in cm2 ?What is the actual area in m2?
Answer:
Step-by-step explanation:
4 cm × 1000 = 4000 cm = 40 meters
3 cm × 1000 = 3000 cm = 30 meters
A 4 cm by 3 cm section on the map represents 40 m by 30 m.
area = 40 m × 30 m = 1200 m²

Use ≈ 3.14 and round your answer to the nearest hundredth.
Answer:
3,052.08 cm^3
Step-by-step explanation:
Here, we want to find the volume of the sphere
We have the formula as;
V = 4/3 * pi * r^3
The radius is 9 cm
V = 4/3 * 3.14 * 9^3
V = 3,052.08 cm^3

the sequence of the numbers below is missing an eighth value. which of the following is the missing value? sequence: 5, 6, 8, 11, 15, 20, 26, __, 41
Answer:
D - 33
Step-by-step explanation:
From 5 to 6, the number is increasing by 1. Then from 6 to 8, it increases by 2. From 8 to 11 it increases by 3. This pattern continues throughout the entire sequence. Since between 20 and 26, it increases by 6, 26+7 should equal the number between 26 and 41. This number would be 33.
An oven is set at 176.8°C. Marla increases the temperature by 23.8°C.
What is the final oven temperature?
Answer:
200.6 degrees Celsius
We have the given number, 176.8 degrees Celsius, and we add or increase it by 23.8 degrees.
176.8 + 23.8 = 200.6
Our final answer is 200.6 degrees Celsius.
~Hope this helps~
Answer:
200.6'C or 461.2'F
Step-by-step explanation:
176.8'C
+ 23.8'C
--------------
200.6'C
To make 'F, we must add 30, then multiply by 2.
200.6'F
+ 30.0'F
--------------
230.6'F

35. The distance between two cities on a map is 3.5 centimeters. The map uses a scale
in which 1 centimeter represents 20 kilometers. What is the actual distance
between these two cities in kilometers?
Answer:
The distance between two cities is 70 km.
Step-by-step explanation:
Given that,
The distance between two cities on a map is 3.5 centimeters.
It is also mentioned that the map uses a scale in which 1 centimeter represents 20 kilometers.
We need to find the actual distance between these two cities in kilometers.
1 cm = 20 km
3.5 cm = (3.5 × 20) km
= 70 km
Hence, the distance between two cities is 70 km.
Name the steps of solving 5x+4=40
Answer:
Step-by-step explanation:
Simplifying
5x + -4 = 40
Reorder the terms:
-4 + 5x = 40
Solving
-4 + 5x = 40
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 5x = 40 + 4
Combine like terms: -4 + 4 = 0
0 + 5x = 40 + 4
5x = 40 + 4
Combine like terms: 40 + 4 = 44
5x = 44
Divide each side by '5'.
x = 8.8
Simplifying
x = 8.8

A radius of a circle is perpendicular to a chord if and only if it
A. is equal in length to that chord
B. parallels that chord
C. bisects that chord
D. intersects the chord directly on the circumference
Answer:
C. bisects that chord
Step-by-step explanation:
The radius of a circle is perpendicular to a chord if and only if it bisects the chord. Therefore, the option b is correct.
Radius of the circle:In the case when the diameter or the radius should be perpendicular with respect to the chord so it should be bisected the chord also its arc.
At the time when the two chords should be congruent so their corresponding arc should also be congruent.
Therefore, the option b is correct.

Justin plans to spend $35 on sports cards. Regular cards cost $4.50 per pack and foil cards cost $6.00 per pack Which inequality shows the relationship between the number of packs of regular cards (r) and the number of packs of foll cards (f) Justin can afford to buy?
Answer:Justin plans to spend $20 on sports cards. Regular cards cost $3.50 per pack and foil cards cost $4.50 per pack
number of packs of regular cards =r and the number of packs of foll cards = f
Cost of Regular card = 3.50
Cost of 'r' packs of regular card = 3.50r
Cost of Foil card = 4.50
Cost of 'f' packs of Foil card = 4.50f
Justin plans to spend $20 on sports cards so the sum of cost of regular and Foil cards should be less than or equal to 20
The inequality becomes
3.50r + 4.50f <= 20
A-(5,-9)
B-(-9,-5)
C-(-9,5)
D-(-5,9)
