Vertical angles 4x+7 and [5(x-4)] what is the value of x

Mathematics

MArishka [77]3 years ago

Answer:

x = 27

Step-by-step explanation:

Vertical angles are congruent.

5(x - 4 ) = 4x +7

5x - 20 = 4x + 7   {Distributive property}

Add 20 to both sides

5x = 4x + 7 + 20

5x = 4x  + 27

Subtract 4x from both sides

5x - 4x = 27

x = 27

Answer:

x = 27

Step-by-step explanation:

vertical angles are congruent , then

5(x - 4) = 4x + 7 ← distribute parenthesis on left side

5x - 20 = 4x + 7 ( subtract 4x from both sides )

x - 20 = 7 ( add 20 to both sides )

x = 27

Which sentence matches the mathematical equation? p-0.40p=0.60p
IRISSAK [1]
P-0.40p = 0.60p

C. Decrease by 40% is the same as multiply by 60%.

Assume that p = 10

10 - 0.40(10) = 0.60(10)
10 - 4 = 6
6 = 6

Based on the above assumption. 40% of 10 is 4 ; and 60% of 10 is 6. So, 10 less 4(40% of 10) is equal to 6 (60% of 10). 

Percentage is used because 0.40 and 0.60 will be multiplied with 100% to get the equivalent percentage 0.40 x 100% = 40% ; 0.60 x 100% = 60%

Given h(x) =3x-4 find x if h(x) =17
NikAS [45]

Answer:

x=7

Step-by-step explanation:

h(x) = 17 so you would input 17 for h(x). The equation should look like this. 17= 3x-4. Add 4 to both sides changing the equation to 21 = 3x. Finally divide both side by 3 and you should get x = 7.
