Answer:
x = 4
Step-by-step explanation:
(6x - 3)° = (2x + 13)° are vertical angles that equal each other get x by itself and solve for x.
(6x - 3)° = (2x + 13)°
6x - 2x = 13 + 3
4x = 16
x = 4
Substitute x for the angles.
(6x - 3)° = ?
(6*4 - 3)° = ?
(24 - 3)° = 21°
(2x + 13)° = ?
(2*4 + 13)° = ?
(8 + 13)° = 21°
Answer:
Step-by-step explanation:
we are given the base area and the height of a solid figure
since the base area is not perfect square
we assure the solid figure to be a cuboid
remember that,
we are given l×w is 40 and h is 7
so substitute
simplify multiplication:
hence,
the volume of the figure is 280 in³
<h2>a) 16y</h2><h2>b) 8y</h2>
a) First, multiply the numbers 8 and 2, and we get 16.
Now, we have to multiply 16 and the algebraic notation “y”, we get the result of 16y.
<h3><u>
Whenever you multiply the number(s) with algebraic notations, you need to multiply the number(s) and write the algebraic notation at the end.</u></h3>
<u></u>
b) Multiply the number 8 and the algebraic notation “y”, and we get the result 8y.

3(100-b) = 6b
300-3b = 6b
+3b +3b
300 = 9b
/9 /9
b=33.33333... or 33 1/3

4[3 * (-2) + 7] / [4 + (-2)]
= 4(-6 + 7) / (2)
= 4(1) / 2
= 4/2
= 2
Answer is B. 2
