Answer:
Y=112 x=45
Step-by-step explanation:
y+68=180
so 180-68=112
y=112
y+(4x-2)+30=180
112+(4x-2)+30=180
140+4x=180
-140 to both sides
4x=180
divide by 4 to both sides
x=45

Working simultaneously, four fudge machines complete a big order in 32 hours. All the machines at the fudge factory work at the same pace. a If only half of the machines are working, in how many hours will the order be complete?
If only half the machines are working at the same rate as before, the order will be finished in 64 hours.
When the four big fridges were working simultaneously, they were able to finish the order in 32 hours.
With only half of these fridges, they will only be half as fast. This means that they will complete the order in double the time:
= 32 x 2
= 64 hours
In conclusion, the order will be completed in 64 hours.

Kayla paid $27.50 for a pair of gloves. The cost of the gloves is $8.75 more than the cost of a scarf. Which equation can be used to find the cost of the scarf?
Answer:
You can use subtraction
Step-by-step explanation:
$27.50 - $8.75 = $18.75 (cost of scarf)
-----------------------------------------------------------------------
the gloves cost 27.50 dollars and if the scarf cost 8.75 dollrs more then that means that if we subtract that extra mount we should get the price of the scarf
if $18.75 is the cost of scarf and if gloves are $8.75 more then...
$18.75 (scarf) + $8.75 (extra $) = $27.50 (gloves)

2- Which bottle of juice is the better buy? *

$1.75 for 500 mL
$4.00 for 1000 mL
$7.25 for 2000mL

3- A box of pancake mix suggests using 250 mL of milk and 325 mL of pancake mix. Rita has only 225 mL of pancake mix left in the box. How much milk should she use?
100 mL
125 mL
150 mL
175 mL
4- Of the 1120 spectators at a hockey game, about 80% are home team fans. How many of the spectators are fans of the visiting team?
918
896
224

1. A kite has a width to length ratio of 4:5, so let the width be 4x and the length be 5x. We know that the length is 80 cm. 80 = 5x
Divide by 5.
16 = x.
Now, the width is 4x.
16 times 4 is 64.
The width is 64.
2. Find the unit rate for each juice. The unit rate is ml / dollar.
The first juice has a unit rate of 150 / 1.
The second has a unit rate of 500 / 1.75.
The third has a rate of 1000 / 4.
The fourth has a rate of 2000 / 7.25
Put all values into a calculator. (First: 150, Second: 285.714285, Third: 250, Fourth: 275.862068966)
Whichever one can buy the most ml for a dollar is the best buy.
In here, that is the SECOND rate, which is 1.75 for 500 ml.
She earns 3% commission on all her sales, so if s represents her sales, she'd earn .03s. Inhere, she sells $950 in total. That is her total sales.
So you plug $950 into the equation as s.
.03 (950) = 28.5
She earned $28.50.
Poor Maya!
3. You set it up in ratios. She needs 250 mL of milk for every 325 mL of pancake mix. 250 milk / 325 mix.
But she only has 225 mix.
So you set up 250 milk / 325 mix = M milk / 225 mix
As in all proportions, you cross multiply.
250 x 225 = 325 x M
56250 = 325M
Divide by 325 on both sides.
173.076923077 = M
She needs about 175 mL. The fourth choice.
4. There are a total of 1120 spectators, made of only home team fans and visiting team fans.
There is a total of 100% of people, and 80% are supporters of the home team, so to find the supporters of the visiting team you subtract 100% by 80%.
100 - 80 = 20.
So 20% of the spectators are supporters of visiting team. Now 20% of the total, and 20% = .20.
.20 x 1120 = 224
224 people are fans of the visiting team.
5. A 500-mL bottle of insect repellent has 22 mg of DEET, a chemical used to keep mosquitos away. The same insect repellent sells in 710-mL bottles. Which of the following proportions can be used to find the amount of DEET in the larger bottle? *
If a 500 mL bottle has 22mg of DEET, then 500ml / 22mg
So set up the equation 500 / 22 = 710 / x
Now, cross multiply.
500x = 710 times 22.
500x = 15620
Divide by 500.
x = 31.24
Other possible proportions are:
22 / x = 500 / 710
x / 22 = 710 / 500
22 / 500 = x / 710
