FInding the length of EB

larisa86 [58]

Answer:

EB=3.3

Step-by-step explanation:

From the diagram, triangle ABC is similar to triangle DBE.

This means that, the corresponding sides are proportional.

It was given that AC=6, DE=4, CB=5.

We want to find EB=x

Since the ratio of corresponding sides are proportional, we have:

$\frac{EB}{CB} =\frac{ED}{AC}$

We substitute to obtain:

$\frac{x}{5} =\frac{4}{6}$

Multiply both sides by 5 to get:

$x=\frac{4}{6}\times 5=\frac{20}{6}=\frac{10}{3}=3.3$

Hey, can anyone help me with this? Okay, so in the equation 10 + 3x= -17 . The answer or (x) = -9 because you minus 10 on both s

Delvig [45]

Answer:

You do -17 + -10 inorder to change the operation used because both negatives does not mathematically look nice.

Step-by-step explanation:

To isolate the unknown, we need to move all the numbers on one side of the equal sign and all the unknow variables on one side.

Here we move 10 on the other side by taking away 10 both sides

10 + 3x = -17

-10 -10

then we are left with only 3x on one side and -27 on the other side because -17 - -10 = -27 , in this case it is acknowledge to change the operation from minus to add because the two minus are together, so we say -17 + -10 .

3x = -27

/3 /3

x = -9
