I will mark brainliest, please help !!

Elena L [17]

Answer:

x = 5/(a-b+3)

Step-by-step explanation:

ax+3x=bx+5

Collect all the terms that has x:

ax-bx+3x = 5 (Subtracting bx both sides)

Take out the x!

x(a-b+3) =5

Divide (a-b+3) both sides to solve for x

x = 5/(a-b+3)

Hope this helps!

Would really appreicate the brainliest!

Solve for x <br> triangle abc is similar to triangle aed

3241004551 [841]

Answer:

9/5 or 1.8

Step-by-step explanation:

triangle aed is larger than triangle abc by a scale factor of 5; we know this because side ed is 5 units and cb, the corresponding side in triangle abc, is 1. if ad has a length of 9, the length of ab must be 9 divided by five. thus, z is equal to 9/5 or 1.8.

For the 50 students in an art contest, there will be 1 prize for first-place, 1 prize for second-place, and 3 prizes for honorab

Sonja [21]

Step-by-step explanation:

there are 50 students and 5 prizes (1 + 1 + 3).

so, already in natural language we would say "there is 1 prize for every 10 students".

formally, remember the rule of probability : desired outcomes over total possible outcomes.

this is here

5/50 = 1/10 = 0.1

your can see it also this way :

if there was only 1 prize, each student would have a chance of 1/50 of winning.

now there are 5 prizes, which gives everybody 5 times the chance of winning. which is then 5×1/50 = 5/50 = 0.1

In triangle ABC, side AB has a length of 8 cm and side BC has a length of 5 cm. If the triangle has an area of 10 square centime

Vesna [10]

Recall the following formula:

Given a triangle with side lengths a, b, and c. Let the measure of the angle between sides of length a and c be B.

Then, the area of the triangle is given by :

$Area= \frac{1}{2}\cdot a\cdot c \cdot \sin B$ .

In our example we have: Area=10 square cm, a=8 cm, c=5 cm, and we want to find the measure of the angle between the 2 sides a and c.

Substituting in the formula we have:

$10= \frac{1}{2}\cdot 8\cdot 5 \cdot \sin B$

Thus, $10=20 \sin B$ , which means $\sin B = \frac{1}{2}$ .

$\frac{1}{2}$ is the sine of $30^{\circ}$ , but also $150^{\circ}$ .

Answer: both 30, and 150 degrees are possible
