Answer:

Step-by-step explanation:

1. All triangles add up to 180°, so you can make an equation like this:

$60.8+57.1+A=180\\117.9+A=180\\A=62.1$

2. As for which angle corresponds to ∠A, we know that ∠A is across from ∠B which is 60.8°. We know that in the other triangle, ∠Z=60.8° as well and ∠Y is right across from it. Therefore, ∠Y corresponds to ∠A.

3. It would be useful to know the options you have for this one. I'd say they're similar (if that's an option).

C) 0.2(x + 5) + 1 = 7

swat32

Answer:

x = 25

Step-by-step explanation:

Given

0.2(x + 5) + 1 = 7 ( subtract 1 from both sides )

0.2(x + 5) = 6 ( divide both sides by 0.2 )

x + 5 = 30 ( subtract 5 from both sides )

x = 25

Use simultaneous equations solve the following problem.

Genrish500 [490]

Let E represent English test and M represent Math test.

M + E = 164

+ M - E = 22

2M = 186 eliminated E by adding the two equations

M = 93 divided both sides by 2

Now, plug that value into either of the equations to solve for E.

M - E = 22 → 93 - E = 22 → -E = 22 - 93 → -E = -71 → E = 71

Answer: Math = 93, English = 71

Write the inequality: The sum of x and 10 is less than -4

andrezito [222]

Answer:

x + 10 < -4

Step-by-step explanation:

x + 10 is less than -4, so -4 would have to be greater. You would put x + 10 on the left side and on the right side would be -4. In between would be a less than sign because x + 10 is LESS than -4.

Connie's dog fido weighs 35 pounds. Her vet placed fido on a diet. What inequality can you write to find the average number of p

lawyer [7]

Fido's dog must lose 1.17 pounds each month to reach healthier weight.

Step-by-step explanation:

Given,

Weight of fido's dog = 35 pounds

Time period = 6 months

Goal weight to reach = 28 or less pounds

Let,

m be the weight to be lose each month.

Weight of dog - Time period * Weight to lose each month ≤ Goal weight

$35-6m\leq 28\\-6m\leq 28-35\\-6m\leq -7$

Dividing both sides by -6

$\frac{-6m}{-6}\leq \frac{-7}{-6}\\\\m\leq 1.17$

Fido's dog must lose 1.17 pounds each month to reach healthier weight.
