Answer:
Its c. c = 50.
Step-by-step explanation:
First, we need to figure out what the equation equals.
7 + 7/7 + 7*7 - 7 = x
PEMDAS
Parentheses, exponents, division/fraction, addition, subtraction.
7/7 = 1. So equation changed into 7 + 1 + 7*7 - 7 = x.
7*7 = 49. So equation changed again into 7 + 1 + 49 - 7.
Lets calculate it. 7 + 1 = 8 + 49 = 57 - 7 = 50. x = 50.
c is the only one who has a calculation of 50.

During an exploratory activity, a student measured the diameter and circumference of several circular objects. She recorded her data in the table below. What equation best represents this data?
y = 6.28x
y = 3.14x + 6.28
y = 3.14x
y = 6.28x + 3.14
Answers
Answer:
y=3.14x
Step-by-step explanation:
if you graph this on a calculator you can just visually see what line lines up with all the points. but you can also plug in one of the points into the equations to see if its true or not and if its true choose that equation. like use the first points (2, 6.28) and plug them into the equations and see which one is true.
The equation best represents the given data is y=3.14x. Therefore, option C is the correct answer.
Given that, a student measured the diameter and circumference of several circular objects.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)
From the table we have (2.0, 6.28) and (5.3, 16.64)
Now, slope = (16.64-6.28)/(5.3-2.0)
= 10.36/3.3
= 3.14
Substitute m=3.14 and (x, y)=(2.0, 6.28) in y=mx+c, we get
6.28=3.14(2.0)+c
c=0
Substitute m=3.14 and c=0 in y=mx+c, we get
y=3.14x
The equation best represents the given data is y=3.14x. Therefore, option C is the correct answer.

Answer:
27°
Step-by-step explanation:
XWY and VWY are supplementary
∴ XWY + VWY = 180°
∴ XWY = 180° - VWY
XYW and ZYW are supplementary
∴ XYW + ZYW = 180°
∴ XYW = 180° - ZYW
ΔXWY is a right triangle at X
∴ XWY + XYW = 90°
∴ 180° - VWY + 180° - ZYW = 90°
∴ 180° - 6x + 180° - 4x = 90°
∴ 360° - 10x = 90°
∴ 10x = 270°
∴ x = 27°

Answers
Answer:
Step-by-step explanation:
Let cats = x and dogs = y
and given conditions are ,
dog: cat= 1:2
y:x=1:2
y/x = 1/2
x=2yalso given that
total animals = 21
x+ y=21 putt x=2y we get2y +y =21
3y = 21
y = 7 Dogsputt y = 7 in above equation we get
x+7=21
x=14 CatsEvery one dog there are two cats 1:2
Also could be written as (cats) 7:12 (dogs)

Gio baked 21 cupcakes for the holiday sale. He made some with vanilla icing, and some with mint-chip icing. He charged $2 for the vanilla cupcakes, and $4 for the mint-chip cupcakes and made $54. How many of each did he make? He created the following system of equations to find out how many of each he made. Let x represent the number of vanilla cupcakes, and y represent the number of mint-chip cupcakes.
x+y=21
2x+4y=54
Answers
$2(15) + $4(6) = $54
Answer: 15 vanilla and 6 mint
Step-by-step explanation:
You would solve for x and get x=21-y and then plug that into the next equation and get 2(21-y)+4y = 54.
You would then solve for y.
42-2y + 4y = 54
42+2y =54
Then subtract 42 from both sides.
2y = 12, and then divide by 2.
You get y=6.
Then we know we sold 21 cupcakes so
21-6=x
15=x
