Answer:
x = - 3/7
y = - 8/7
Step-by-step explanation:
(2x - 6y = 6)/2 =
x - 3y = 3
x = 3y + 3
Substitution:
6 (3y +3) - 4y = 2
18y + 18 - 4y = 2
14y = -18+2
y = -16/14
y = - 8/7
Substitution:
x = 3(-8/7)+3
x = -24/7 + 3
x = -3/7
The surface area of the monument shaped like a square pyramid is 14 m².
<h3>
Area </h3>
Area is the amount of space that is occupied by a two dimensional shape or object.
From the diagram
Area of each triangle = (1/2) * base * height = (1/2) * 2 * 2.5 = 2.5 m²
Area of square = length * length = 2 m * 2 m = 4 m²
Surface area of monument = 4(2.5) + 4 = 14 m²
The surface area of the monument shaped like a square pyramid is 14 m².

Melinda would live 14 blocks from her grandparents. you would add 6&8 to get that answer
Answer:
20 degrees
Step-by-step explanation:
Since angle B and angle A are both inscribed angles to the same arc, they must be equal. Therefore:
7x-8=5x
Subtract 5x from both sides:
2x-8=0
Add 8 to both sides:
2x=8
Divide both sides by 2:
x=4
Now, you can plug this back into the equation for angle B:
B=7(4)-8
B=28-8
B=20
Hope this helps!
Answer:
He will earn 9$ annually.
Step-by-step explanation:
To find his earning we will put the numbers in the the exponential equation y=a+(b+c)^x
A=90
B=1.10 (you always add 1 to your percentage when it is positive)
C=0
X=1
Y=90+(1.1)^1
Y=9
