Answer:

x = 6

Step-by-step explanation:

2x + 3(3x - 5) = 51

Expand the brackets.

2x + 9x - 15 = 51

Add like terms.

11x - 15 = 51

Add 15 on both sides.

11x = 51 + 15

11x = 66

Divide both sides by 11.

x = 66/11

x = 6

6/8 divide by 8/12<br> A. 9/2<br><br><br> B. 8/9<br><br><br> C. 9/8<br><br><br> D. 9/32
Musya8 [376]

Answer:

C. 9/8

Step-by-step explanation:

\frac{6}{8}  \div  \frac{8}{12}

Use KCF which means Keep the first fraction, Change the second fraction by flipping it and change the division sign to a multiplication symbol:

\frac{6}{8}  \times  \frac{12}{8}

multiply the numerator together:

6 × 12 = 72

multiply the denominator together:

8 × 8 = 64

now the fraction is:

\frac{72}{64}

simplify further by dividing both numbers by 8:

72 ÷ 8 = 9

64 ÷ 8 = 8

so the fraction is 9/8

If the length of a cuboid is 60cm and width 40cm and its surface area is 14800cm² find its height
kherson [118]
Formula of surface area of cuboid = 2(lb+bh+lh) . Surface area of cuboid is 14800cm^2 (Given) then 14800 = 2(60*40+40*Height+Height*60) 14800= 2(2400+40*H+H*60) 14800= 4800+80*2H+2H*60 14800= 4880*4H*60 14800/4880*60= 4H
14800/292800=4H
7400/146400=4H
3700/73200=4H
1850/36600=4H
925/18300=4H
185/3660=4H
37/732=4H
37/732*4=H
37/2928=H
H= 79.1351351
