I do agree because -2 3/4 can't be greater since it's a negative amount so Rover is losing it, while Spot is gaining weight since 2 1/2 is positive.
Answer:
x=3, Aly is correct.
Step-by-step explanation:
a. angle YWZ
b. ZY = 9
c. the triangles are congruent so 7x-20=2x-5, 5x=15, and x=3
Answer:
Anna received $1000
Barbara received $600
Chrissy received $400
Step-by-step explanation:
Let us solve the problem
∵ The ratio of Anna, Barbara, and Chrissy is 5: 3: 2
∵ Barbara received $400 less than Anna
→ That means Anna - Barbara is 400, find the difference between their ratio
∵ The difference between their ratio = 5 - 3 = 2
→ By using the ratio method
→ Anna : Barbara : difference
→ 5 : 3 : 2
→ A : B : 400
→ By using the cross multiplication
∵ A × 2 = 5 × 400
∴ 2A = 2000
→ Divide both sides by 2
∴ A = 1000
∴ Anna received $1000
∵ B × 2 = 3 × 400
∴ 2B = 1200
→ Divide both sides by 2
∴ B = 600
∴ Barbara received $600
Let us use the ratio between Anna and Chrissy to find the amount of Chrissy
→ Anna : Chrissy
→ 5 : 2
→ 1000 : C
→ By using cross multiplication
∵ 5 × C = 2 × 1000
∴ 5C = 2000
→ Divide both sides by 5
∴ C = 400
∴ Chrissy received $400
ANSWER
![B.\text{ }18](https://tex.z-dn.net/?f=B.%5Ctext%7B%20%7D18)
EXPLANATION
Let us make a sketch of the square:
Each angle in a square is equal to 90 degrees. This implies that:
![5x=90](https://tex.z-dn.net/?f=5x%3D90)
Solve for x by dividing both sides of the equation by 5:
![\begin{gathered} \frac{5x}{5}=\frac{90}{5} \\ \\ x=18 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7B5x%7D%7B5%7D%3D%5Cfrac%7B90%7D%7B5%7D%20%5C%5C%20%20%5C%5C%20x%3D18%20%5Cend%7Bgathered%7D)
The answer is option B.
