Can you guys please help me with 4,5,6 and 10 please

4.) 63

Step-by-step explanation:

4x = 7(36)

4x = 252

Divide both sides by 4 to isolate X

X = 252/4

X = 63

Plug in 63 for X to double check

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

25/6

step-by-step explanation:

you multiply 4 by the denominator (4*6=24) and add it to the numerator which makes it 25/6.
