Complete the solution of the equation. Find the
value of y when x equals 15.
-3x - y = -51
Answer:
The solution of the equation y = 36
Step-by-step explanation:
Explanation:-
Given equation -3x-y =-51
Given that x =15 in equation -3x-y=-51
⇒ - 3(15) - y = -51
⇒ - 15 - y =-51
⇒ -15+ 51 = y
⇒ y = 36

Answer:
Perimeter of the rectangle = 6 x +20
Perimeter of the rectangle = 0 x² + 6 x + 20
Step-by-step explanation:
Step(i):-
Given that the length of the rectangle = 2x +3
Given that the width of the rectangle = x +7
Perimeter of the rectangle = 2(length + width)
Step(ii):-
Perimeter of the rectangle = 2(length + width)
= 2(2 x +3 + x+7)
= 4x +6+2x+14
= 6 x +20
Final answer:-
Perimeter of the rectangle = 6 x +20
Perimeter of the rectangle = o x² + 6 x + 20
How can you check to see if two ratios form a proportion? Explain the method you used to find the answer to the previous problem.
Answer:
Step-by-step explanation:
A proportion is simply a statement that two ratios are equal. In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
Answer:
Write a proportion using the ratios. Find the cross products. If the cross products are equal, then the ratios form a proportion.

What is the area of the triangle?
7
4
8
units2
Answer:
14 units²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 7 and h = 4 , so
A = [tex]\frac{1}{2}[/tex] × 7 × 4 = [tex]\frac{1}{2}[/tex] × 28 = 14 units²

Answer:
The price of ribbon is $0.63 per meter.
Step-by-step explanation:
It is given that:
Cost of 3 meter ribbon = $1.89

Unit price per meter = $0.63 per meter
Therefore,
The price of ribbon is $0.63 per meter.
1.V Diferența a două numere este 38, iar descăzutul este 76. Scăzătorul este:
a. 38;
b. 29;
d. 83.
-
C. 114;
Răspuns:
38
Explicație pas cu pas:
Dat fiind :
Diferența dintre numere = 38
Subtractorul = x
Scădere = 76
Diferența dintre numere;
Scădere - scădere = diferență
76 - scădere = 38
76 - 38 = subtractor
Subtractor = 38
Find the x-intercept and
the y-intercept from the
following linear equation:

Step-by-step explanation:
X-intercept:
7x+3(0)=63
7x=63
x=9
y-intercept:
7(0)+3y=63
3y=63
y=21

solve . 15 - 10x = 5(x + 9) show your work
Answer:
x= -2
Step-by-step explanation:
Let's solve your equation step-by-step.
15−10x=5(x+9)
Step 1: Simplify both sides of the equation.
15−10x=5(x+9)
15+−10x=(5)(x)+(5)(9)(Distribute)
15+−10x=5x+45
−10x+15=5x+45
Step 2: Subtract 5x from both sides.
−10x+15−5x=5x+45−5x
−15x+15=45
Step 3: Subtract 15 from both sides.
−15x+15−15=45−15
−15x=30
Step 4: Divide both sides by -15.
−15x/-15 = 30/ -15
x= −2

A study of a population of 1,200 frogs revealed that 12 out of every 180 frogs in the population have spots on their back. Based on the results of this study, how many frogs do not have spots on their back? Explain.
Answer:
80 spotted frogs
Step-by-step explanation:
We can write a ratio
spotted frogs:frogs
12:180
x:1200
To solve we just multiply 12*6.66667 (because this is what we multiplied 180 to get to 1200)
the answer is 80
