Answer:

145°

Step-by-step explanation:

x°+70°=(2x-5)°

x°+70°=2x°-5°

70°+5°=2x°-x°

75°=x°

x=75

JKM=(2x-5)°

=(2x75-5)°

=(150-5)°

=145°

Answer:

The area of trapezoid is 32cm².

Step-by-step explanation:

Given that the area of trapezoid formula is A 1/2×(a+b)×h where a, b represents length and h is height :

$A = \frac{1}{2} \times (a + b) \times h$

$let \: a = 4,b = 12,h = 4$

$A = \frac{1}{2} \times (4 + 12) \times 4$

$A = \frac{1}{2} \times 16 \times 4$

$A = 8 \times 4$

$A = 32 \: {units}^{2}$

From 12x - 6y + 9z subtract -x -3z + 6y . A) 12z - 13x - 12y B) 13x + 12y + 12z C) - 13x - 12y - 12z D) 13x - 12y

seraphim [82]

12x - 6y + 9z - (-x - 3z + 6y) = 12x - 6y + 9z + x + 3z - 6y = 13x - 12y + 12z

Twelve ounces of Brand X costs $1.14. Sixteen ounces of Brand Y costs $1.28. Brand X costs how much more per ounce than Brand Y.

bearhunter [10]

"Per" means "divided by", so "cost per ounce" means "cost"/"ounces".

The difference in cost per ounce is
.. (1.14/12) -(1.28/16) = .095 -.08 = 0.015

Brand X costs 1.5¢ more per ounce than Brand Y.

Find the x intercept (s) of the line <br> Y= -8x-16

Bess [88]

when you find x-intercept, you are finding the coordinate when y=0, hence sub y=0,

-8x-16=0

8x=-16

x=-2
