Answer:

C. 61

Step-by-step explanation:

Two sides are equal, so the triangle is an isosceles triangle.

Both base angles are equal.

Angles in a triangle add up to 180 degrees.

58 + x + x = 180

58 + 2x = 180

2x = 122

x = 61

Answer:

${ \tt{( {x}^{2} + 5x + 2) - (5 {x}^{2} - x - 2) }} \\ = { \tt{(1 - 5) {x}^{2} + (5 + 1)x + (2 + 2)}} \\ = { \tt{ - 4 {x}^{2} + 6x + 4 }} \\ = { \tt{ - 2(2 {x}^{2} - 3x - 2) }}$

Need urgent help in mathematics!! Will mark brainliest!!!!

Simply find the total medium cofees sold
then divide that by the number of medium cofees that weren't caffeinated

so..
$66 \div 44 = x$
then
$100 \div x = percentage$

so x will be 1.5 & 100 ÷ 1.5 = 66.666...
rounded is 67%

$67\%$

Solve the system of equations<br> 3x+4y+12<br> 9x-2y=15

Mrrafil [7]

3x+4y=12
9x-2y=15
we will use elimination
multiply 3x+4y=12 by -3

-9x-12y=-36
9x-2y=15
_________ add
-14y=-21
÷-14 both sides
y=1.5
find x
3x+4 (1.5)=12
3x+6=12
-6 both sides
3x=6
÷3 both sides
x=2

x=2
y=1.5
