Step-by-step explanation:
4x + 8y = 40
4x + (8×0.8) = 40
4x + 6.4 = 40
4x = 33.6
4x÷4 = 33.6 ÷ 4
x = 8.4
Step-by-step explanation:
Angle XBC = 55 degrees because it is a corresponding angle with Angle AXC
and corresponding angles are equal or congruent.
Ok so angle XBC = 55 degrees and since this an isosceles triangle
XBC = XCB which means XCB = 55 degrees
Now to find angle BXC we know that all angles of a triangle add up to 180 degrees.
Angle XBC + Angle XCB + Angle BXC = 180 degrees
Let x represent angle BXC
55 + 55 + x = 180
110 + x = 180
x = 180 - 110
x = 70
∴ Angle BXC = 70 degrees
The answer is 31.4 I remember doing this
Answer: 30
Step-by-step explanation: If she has 6 on one side, the that would mean there is 6 on at least 1 other side. And to make up for the remaining 10 feet or trim, we would get 5 and 5. So her quilt is 6x5 and we can use that equation to get the number of blocks, too. So 6x5=30.
Answer:
90000
Step-by-step explanation:
because 10^4 = 10,000
then 9 x 10,000 = 90,000
