Answer:

Step-by-step explanation:

10 tests = x tests

Answer:

18 tests

Step-by-step explanation:

Create a proportion where x is the number of tests after 9 weeks:

$\frac{10}{5}$ = $\frac{x}{9}$

Cross multiply and solve for x:

5x = 90

x = 18

So, after 9 weeks, Vera will have taken 18 tests

A train is going on a journey. First it travels east for 50 kilometers. Then it turns north and travels for 22

Igoryamba

The train travel 20 kilometers in the southward direction to reach its original location.

Step-by-step explanation:

The given is,

First train travels east for 50 kilometers, then

Turns north and travels for 22 kilometers

It goes west for 50 kilometers

Step:1

Let, A - Distance of train travels from its starting point in Eastern direction at pq point

B - Distance train travels in northward direction at qr point

C - Distance of train travels in western direction at rs point

D - Distance of train travels in southward direction to reach its starting location at sp point

Step:2

Refer the attachment,

Distance of travel in northward direction and distance of travel in southward direction are equal.

qr = sp.............. (1) ( ∵ Eqn (1) from the Diagram)

20 km = 20 km

sp = 20 km

Result:

So, the distance of train travel to reach its original location in southward direction is 20 km.

Last season he scored 179 touchdowns. This season he scored 253 touchdowns.

nydimaria [60]

Given,
Previous Season touchdowns scores = 179
Current Season touchdowns scores = 253
Here,
Increased touchdowns scores = 253 - 179 = 74
Now,
Percent increment = (increased/previous)*100 = (74/179)*100 = 41.34%
Hence, the required answer is 41% ( nearest round off percent)

Simplify the linear expression

vekshin1

Answer:

$\huge\boxed{-\frac{7}{8}a - \frac{1}{6}}$

Step-by-step explanation:

This question utilizes combining like terms and common denominators. First you have to convert both terms including "a" to have a denominator of 8. You would do this by multiplying both the numerator, and the denominator by the same value. This value in the case of $-\frac{1}{4} a$ would be 2, and in the case of $\frac{2}{3}$ the value would be 2. This would result in the equation: $-\frac{5}{8}a+\frac{4}{6}-\frac{2}{8}a-\frac{5}{6}$ . Then simply combine like terms to get your final answer.
