The surface area of the cuboid is 276 in².

Solution:

Given data:

Length of the cuboid = 10 in

Width of the cuboid = 4 in

Height of the cuboid = 7 in

<u>To find the surface area of the cuboid:</u>

Surface area of the cuboid = 2(lw + wh + lh)

= 2(10 × 4 + 4 × 7 + 10 × 7)

= 2(40 + 28 + 70)

= 2(138)

= 276 in²

The surface area of the cuboid is 276 in².

tax on the original price of a bicycle is charged at 20% of the original price. After tax has been included, Mathew pays $1080 f

kicyunya [14]

Answer:

Original price of bicycle = $864

Step-by-step explanation:

Given:

Rate of tax = 20%

Price pay by Mathew = $1,080

Find:

Original price of bicycle

Computation:

Original price of bicycle = Price pay by Mathew[1 / (1-20%)]

Original price of bicycle = 1,080[1 / (1-20%)]

Original price of bicycle = 1,080[1 / (1-0.2)]

Original price of bicycle = 1,080[1 / (0.8)]

Original price of bicycle = 1,080[1.25]

Original price of bicycle = $864

-7(n - 2) + 2n = -5(n + 6)

skad [1K]

Given the expression below

$-7(n-2)+2n=-5(n+6)$

To find n

Open the brackets

$\begin{gathered} -7(n-2)+2n=-5(n+6) \\ -7n+14+2n=-5n-30 \\ -7n+2n+14=-5n-30 \\ -5n+14=-5n-30 \end{gathered}$

Collect like terms

$\begin{gathered} -5n+14=-5n-30 \\ -5n-(-5n)=-30-14 \\ 0\ne-44 \end{gathered}$

Since, the sides are not equal,

Hence, there is no solution

Three times a number minus thirty-two

lbvjy [14]

Answer:

3n−32=7n+28

n=-15

Step-by-step explanation:

Let's solve your equation step-by-step.

3n−32=7n+28

Step 1: Subtract 7n from both sides.

3n−32−7n=7n+28−7n

−4n−32=28

Step 2: Add 32 to both sides.

−4n−32+32=28+32

−4n=60

Step 3: Divide both sides by -4.

−4n/−4=60/−4

n=−15
