Answer:
a. 2x+4y=100
b. 2 questions
Step-by-step explanation:
For a, you can write out hat equation, which can test if a specific combination will work, and once you have one variable, you can solve another
For b, you can plug 24 into the equation
2x+4(24)=100
2x+96=100
2x=4
x=2

A few boats were traveling upstream and downstream. A satellite recorded the movements of several boats. A motor boat traveled -3.4 miles for every hour in 0.75 hours. How much progress?
Answer:
-2.55 in .75 miles
Step-by-step explanation:
the unit rate is -3.4
so every time it goes up or down it will be the number of hours times -3.4
.75×-3.4=-2.55

Dina has several small clay pots. She wants to display them in order of height, from shortest to tallest. What will be the order of the pots?
Answer:
1. (2.5 2. ( 8 3. (2 1/3 4.(5
Step-by-step explanation:
The correct order from shortest to tallest will be √5 , [tex]2\frac{1}{3}[/tex] , 2.5 , √ 8.
It is given that Dina has several small clay pots arranged in a order.
We have to rearrange them in correct order from shortest to tallest.
What will be the correct order from greatest to least for fractions ; 1/2 , 2/2 , 3/2 , 4/2 , 5/2 , 6/2 ?
The correct order will be ; 6/2 , 5/2 , 4/2 , 3/2 , 2/2 , 1/2.
Expressing the given numbers/fractions in decimal form.
√ 8 = 2.82 which is the tallest,
2.5 = 2.5 is second tallest,
[tex]2\frac{1}{3}[/tex] = 2.33 which is third tallest,
√5= 2.23 which is the shortest.
Thus , the correct order from shortest to tallest will be √5 , [tex]2\frac{1}{3}[/tex] , 2.5 , √ 8.

Containers of oats are prepared in advance for a baking project. Later, raisins are added to the oats to make granola bars. This table shows the rate relationship between oats and raisins.
Cups of Oats (x) Cups of Raisins (y)
1
0.5
2
1
3
1.5
4
2
5
2.5
Which answer choice includes both a function that describes this relationship and correctly explains how?
y = 2 x, because the recipe calls for a ratio of 2 cups raisins per cup of oats.
y = x , because the recipe calls for a rate of 1/2 cup raisins per cup of oats.
y = x , because the recipe calls for a rate of 2 cups raisins per cup of oats.
y = 2 x, because the recipe calls for a rate of 1/2 cup raisins per cup of oats.
Answer:
2y=x
For every two cups of oats there's one cup of raisins.
Step-by-step explanation:
1÷2=0.5
2÷2=1
3÷2=1.5
4÷2=2
5÷2=2.5
There's twice the ampunt of oats compared to raisins.

Which equation has infinitely many solutions?
A. -6.8 + 3y + 2.4 = 4.3 – 3y
B. 1/3y + 2.5 – 2/3y = 1.2
C. 5.1 + 2y + 1.2 = -2 + 2y +8.3
D. 2/5y = 2.3 + 3/2y
Answer:
C
Step-by-step explanation:
5.1 + 2y + 1.2 = -2 + 2y + 8.3 ( subtract 2y on each side)
5.1 + 1.2 = -2 + 8.3 ( collect like terms)
6.3 = 6.3
If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers.
Answer:
C. 5.1 + 2y + 1.2 = -2 + 2y + 8.3
Step-by-step explanation:
-6.8 + 3y + 2.4 = 4.3 - 3y **SOLVE FOR y
-4.4 + 3y = 4.3 - 3y
3y +3y = 4.3 + 4.4
6y = 8.7
8.7 DIVIDED BY 6
y = 1.45 THEREFORE, only one solution
1/3y + 2.5 - 2/3y = 1.2 ** TRANSFORM DECIMALS TO FRACTIONS!
1/3y + 5/2 - 2/3y = 6/5 --> multiply both sides by 30
10y + 75 - 20y = 36 --> collect like terms
-10y = 36 - 75
-10y = -39
y = 3.9 or 39/10 one solution
5.1 + 2y + 1.2 = -2 + 2y + 8.3
5.1 +1.2 = -2 + 8.3 ***2y crosses out as their the same!!
6.3 = 6.3 a REAL solution; infinity many
2/5y = 2.3 + 3/2y
2/5y = 23/10 + 3/2y
4y = 23 + 15y
4y - 15y = 23
-11y = 23
y = -2.09 or -23/11 one solution
Hope I helped!!!

Juan and Gloria are comparing the two numbers 354.6 and 354.06. Juan says that 354.06 is equal to 10 x 354.6. Gloria says he is wrong. Do you agree with Juan or Gloria? Explain your thinking.
Juan is incorrect; Gloria is right. 354.06 is not equal to 10 times 354.6 as the zero only changes the decimal place value.
Gloria is accurate while Juan is mistaken. 354.6 and 354.06 do not add up to the same number. It is not possible to get a value that is 10 times the other number (354.6) by adding a zero to the decimal point (354.06).
Only the decimal place value is altered when a zero is added the actual numerical value remains unchanged. Compared to 354.6, which only has one decimal place, 354.06's additional zero after the decimal point indicates a more accurate measurement. Juan was mistaken when he said that 354.06 was equal to 10 times 354.6.

D)73/18
Answer:
A -59/18
or
-3/5/18-3.27...
Step-by-step explanation:
First you wanna calculate the sum
(1/3+1/9)×4²+5/18=
-2/9×4²+5/18
Then you wanna evaluate the power
(1/3+1/9)×4²+5/18=
-2/9×16+5/18
Now you are gonna calculate the product
-2/9×16+5/18=
-32/9+5/18
Last you want to calculate the sum
-32/9+5/18=
-59/18
