B
4.7x+7.9

C
−12.1x+7.9

D
12.1x+7.9

Answers

Answer 1
the answer would be B. 4.7x+7.9
Answer 2

Step-by-step explanation:

so we know that

(8.4x+2.9)+(−3.7x+5)= 4.7x+7.9

so we need an equivelant to 4.7x+7.9

A. −4.7x+7.9= -1/10x(47x-79)

B.=4.7x+7.9=1/10x(47x+79)

C.−12.1x+7.9=-1/10x(121x-79)

D.12.1x+7.9=1/10x(121x+79)

So the answer would be B!

Make h the subject of the formula:
d=√(3h/2)

Answers

Answer:

Do you mean d = √(3h/2)?

Square both sides:

d² = √(3h/2)²

d² = 3h/2

Then, multiply both sides by 2/3 to obtain:

h = 2d²/3

Answers

Answer:

x=8

Step-by-step explanation:

normally it would be 2x-1=[tex]\frac{3}{4}[/tex]x+9 so now we have to combine the x into one fraction which will be 2x-1=[tex]\frac{3x}{4}[/tex]+9 now for my way i will be taking the -1 to the other side and when that happens its going to become positive so now the answer will be 2x=[tex]\frac{3x}{4}[/tex]+10 ok so now we have to have the x's to the same side so i have to drag the fraction to the other side and making it positive which will conclude into 1.25x=10 and now 10 divided by 1.25 is 8 so the answer is x=8 (sorry for the ok nows) hope this helped

The amount of water an electric dishwasher uses to wash dishes varies directly with the number of loads of dishes. The dishwasher uses 32 gallons of water to wash 4 loads of dishes.

How many gallons of water will the dishwasher use to wash 12 loads of dishes?

Answers

Answer:

I believe it 96.

Step-by-step explanation:

32÷4=8

4×8=32

12×8=96

Answer:

96 gallons

Step-by-step explanation:

So to wash 4 loads of dishes, you need 32 gallons.  If you divide 32 by 4 you get 8.  That means you need 8 gallons of water per load.  Since there are 12 loads and you need 8 gallons per load, if you multiply 8 X 12 you get 96.  This means you need 96 gallons of water for 12 loads of dishes.  Hope it helps!

$15 for 5 pairs of socks; $25 for 10 pairs of socks Determine if each pair of ratios or rates are equivalent. Explain your reasoning.

Answers

The ratio rates are not equivalent because they are saying 5 pairs of socks would cost $15 so if you were to buy 10 socks for that price, it would cost 30 dollars but as listed, they are selling it for $25

Answer:

These ratios are not equivalent.

Step-by-step explanation:

If you get 5 pairs of socks for $15, that means that each pair of socks are $3. If you buy 10 pairs of socks for $25, you are spending $12.50 for each pair. If you double the 5 pairs of socks for 10 pairs of socks, you will be spending $30 because you have to add another $15.

So between 10 pairs of socks for $30 (5 pairs of socks for $15) and 10 pairs of socks for $25, you will be spending more on the 5 pairs of socks.

You are spending more money on the 5 pairs of socks for $15.

The graph shows the number of quarts picked and the amount of money the customer paid.

Another customer pays $8.75 for the strawberries she picks. What point (n, a) on the graph represents this?

Answers

Answer:

Step-by-step explanation:

Point (n, a) on the graph represents the number of quarts and the Amount paid(in $).

What is the importance of graphs in our daily life?

Graphs are a popular tool for visually illuminating data relationships. A graph serves the objective of presenting data that are either too many or complex to be fully expressed in the text while taking up less room.

Given, The graph shows the number of quarts picked and the amount of money the customer paid. Another customer pays $8.75 for the strawberries she picks.

Slope of the given graph  = y₂ - y₁ / x₂ - x₁

Slope of the given graph  = 3.5-0 /1-0 = 3.5

As the Graph is passing through the origin point

Hence, the equation of the line will be y = mx

Where slope(m) = 3.5

thus the equation of the given graph  y = 3.5 x

For another customer given, y = 8.75

Hence x = 8.75/3.5

x = 2.5

Coordinates over the graph will be(2.5, 8.75)

Therefore, The number of quarts and the amount paid (in dollars) are represented by the graph's points (n, a).

Joan is 4 feet 2 inches tall. There are 2.54 centimeters in 1 inch. What is Joan’s height in centimeters?

Answers

Answer:

Thus the answer is 127

Step-by-step explanation:

4 feet = 48 inches. 2.54 = 1 inch.

It is found that Joan's  height is 127 centimetres.

What is the fundamental principle of multiplication?

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given that Joan is 4 feet 2 inches tall and we need to change to centimeters .

First we change her height to inches;

1 Foot = 12 Inches

Therefore, 4 Feet = 4 x 12 = 48 inches

The Total height in inches =48 inches + 2 Inches = 50 inches

Now, we have gotten her height in inches, change  to centimetres.

We have that;

1  inch =2.54 centimeters

50inches = 50 x 2.54 cm

=127 centmeters.

Hence, Joan's height is 127 centimetres.

Jeremy bought a $60 pair of sneakers on sale for 15% off. Then, he used a coupon that gave him an additional 10% off. Can Jeremy find the cost of the sneakers by adding the percents?
by finding 25% off of $60, and
by finding 15% off of $60, and then subtracting 10% from that cost.
Complete the explanation.

25% off of $60 is equal to $
.

15% off of $60, then subtracting 10% from that cost, is equal to $
.

Are the two total costs equal? Enter yes or no.

Answers

Answer: No

Step-by-step explanation: you have to subtract 60$ and 15% and then subtract 45$ and 10%. Equals 35$ the total cost.

$60 - 15% is $51 (15% of $60 is 9)
$51 - 10% is $45.90 (10% of $51 is 5.10)
No store can combine two coupons to give you higher percentage of discount . So he will end up paying $45.90 when used both coupons.
