Answer:
i believe its the second part thats wrong
Step-by-step explanation:
1 Distribute
−5(−2+10)=20
10−50=20
2 Add 50 to both sides of the equation
10−50=20
10−50+50=20+50
3 Simplify
Add the numbers
10x−50+50=20+50
10=20+50
Add the numbers
10x =20 + 50
10x=10
4 Divide both sides of the equation by the same term
10x = 70
10x 70
---- = ----
10 10
5 Simplify
Cancel terms that are in both the numerator and denominator
10x 70
---- = ----
10 10
70
x = ----
10
70
x = ----
10
x=7
Solution
= 7

Answer:
The correct answer is two designs are used 12 times each and other four designs are used for 13 times each.
Step-by-step explanation:
Width of the quilt Lu is making is 18 rows of 20 squares each.
Thus the perimeter of the quilt is 20 + 20 + 18 + 18 = 76.
We can also say there are 76 square as the boundary which are to be bordered with toy designs.
Each square can hold 1 design of toy and there are 6 different designs of toys.
Thus number of times each design is used
= 12
.
Thus there are two designs used 12 times each and other four designs are used for 13 times each.
Answer:
20√3 cm
Step-by-step explanation:
Altitude of an equilateral triangle splits it into 2 equal right triangles, it bisects the base and the angle opposite to the base.
<u>Let the altitude be x. Then as per Pythagorean theorem:</u>
- x² = 40² - (40/2)²
- x²= 1600 -400
- x²= 1200
- x= √1200
- x= 20√3 cm
<u>Correct choice is</u> the second one
