For what value of x is angle 1 complementary to angle 2, if m angle 1=5x+4 and m angle 2=7x+2?

1 answer:

6 0

Two Angles are Complementary when they add up to 90 degrees (a Right Angle). They don't have to be next to each other, just so long as the total is 90 degrees.

So (5x + 4) + ( 7x + 2) = 90

12x + 6 = 90

12x = 90 – 6

12x = 84

X = 7

Tasya [4]

Answer:

The total cost for john's meal would be $66.84

Step-by-step explanation:

6.5% of 52.30 = 3.3995

52.30 plus 3.3995 = 55.6995

20% of 55.6995 = 11.14$

55.6995 + 11.14 = $66.84

X=6 is a solution to the inequality x−5≤ 10 True or False?

vekshin1

Answer:

$\boxed{\sf{FALSE}}$

$\boxed{\sf{x\leq 15}}$

Step-by-step explanation:

Isolate the term of x from one side of the equation.

First, add by 5 from both sides.

$\sf{x-5+5\leq10+5}$

Solve.

Add the numbers from left to right.

$\sf{10+5=15}$

$\Longrightarrow: \boxed{\sf{x\leq 15}}$

Therefore, the solution is x≤15, which is our answer.

I hope this helps you! Let me know if my answer is wrong or not.

What is x if y Is 5 x^2 (2y +5)=240

UkoKoshka [18]

X^2(2y+5)=240
x^2(2(5)+5)=240
x^2+(10+5)=240
x^2+15=240
minus 15 both sides
x^2=225
sqrt both sides
x=15
