Put the values of the variables in place of the variables in the expression, then do the arithmetic.

$8p+3q-18\\\\=8\left(\dfrac{1}{2}\right)+3(7)-18=\dfrac{8}{2}+21-18\\\\=4+21-18\\\\=25-18\\\\=\bf{7}$

Find an ordered pair (x, y) that is a solution to the equation.<br><br> x-5y=5

timurjin [86]

Answer:

(x,y)=(0,-1)

Step-by-step explanation:

Observe that the equation $x-5y=5$ can be transformed in the equation of a line

$x-5y=5\\-5y=5-x\\y=\frac{x-5}{5}\\y=\frac{1}{5}x-1$

Since x can take any value then the equation has infinite solutions. But we need only an solution (x,y). Then, taking x=0 we have that $y=\frac{1}{5}*0-1=-1$ .

Therefore the ordered pair (x,y)=(0,-1) is a solution of the equation.

the area of a bathroom floor measures 3 yards by 3 yards and each custom tile that makes up the flooring is 1 1/2 square yards.

wel

Using the area, the number of tiles needed to cover the floor is 6.

The area is the region bounded by the shape of an object.

Therefore, the bathroom floor measures 3 yards by 3yards.

Hence the area of the bathroom floor can be calculated as follows;

area of the bathroom floor = 3 × 3

area of the bathroom floor = 9 yards²

The area of the custom tiles that makes the flooring is 1 1 /2 square yards.

Hence,

number of tiles needed to cover the floor = 9 ÷ 3 /2

number of tiles needed to cover the floor = 9 × 2 / 3

number of tiles needed to cover the floor = 18 / 3

number of tiles needed to cover the floor = 6

1.How much will $5,000 accumulate in 5 years if it earns 6% per annum for the first 3 years and then 8% per annum for the next 2

Pavel [41]

Answer: Amount after 5 years become $5937.60.

Step-by-step explanation:

Since we have given that

Principal amount = $5000

Time period = 5 years

Rate of interest for 3 years = 6%

Rate of interest for 2 years = 8%

so, Amount becomes

$Amount=5000(1+\dfrac{6}{1000})^3(1+\dfrac{8}{100})^2\\\\Amount=5000(1+0.006)^3(1+0.08)^2\\\\Amount=5000(1.006)^3(1.08)^2\\\\Amount=\$5937.60$

Hence, Amount after 5 years become $5937.60.

Write each term as a power of 4 and write the next three terms of the sequence 256, 64, 16 , 4

faust18 [17]

$4^{4}$ , $4^{3}$ , 4², $4^{1}$

continuing the sequence, the next three terms will be

$4^{0}$ , $4^{- 1}$ , $4^{- 2}$

the sequence is 256, 64, 16, 4, 1, $\frac{1}{4}$ , $\frac{1}{16}$
