Answer:
- The correct equation is 6s = 7.80
- The solution of the equation is s = $1.30
Step-by-step explanation:
To find the product of 6 and a number, first we denote the unknown number as s.
The product of 6 and s is the same as 6s.
If the product of both numbers is $7.80, then 6s = $7.80
The correct equation is therefore 6s = $7.80
To get the value of s, we will divide both sides by 6 to have:
6s/6 = $7.80/6
s = $1.30
Based on the calculation, the following statements are true
- The correct equation is 6s = 7.80
- The solution of the equation is s = $1.30
Answer:
C. 20
Step-by-step explanation:
We have to isolate x.
6(x - 8) = 72
Distribute 6.
6x - 48 = 72
Add 48 to both sides.
6x = 120
Divide both sides by 6.
x = 20
Answer:
Step-by-step explanation:
Q no 4 :
4, 8
1, 5
3, 7
2, 6
Q no 5:
(a)
10x + 1 = 12x - 5
1+5= 12x - 10x
2x = 6
x = 6/2
x = 3
(b)
11x - 15 + 5x - 13 = 180 (angles on a straight line)
11x + 5x - 15 - 13 =180
16x - 27 = 180
16x = 180 + 27
16x = 207
x = 207 / 16
x = 12.9375
One minute is sixty seconds.
So we can do 6 times 60 and the answer comes out to 360. It took him 360 seconds to complete the puzzle.
Tot ratio=11
330/11=30
So Ed pay 7x30=210
Fay pays 4x30=120
For Ed to give Fay money so they r equal, he would need to give $45 so that they both are at 165.
