Answer:
The simplified version of this equation is -3x - 12.
Step-by-step explanation:
To simplify this equation, distribute -3 to both x and 4.
-3(x+4) = -3x -12
Answer:
-3x-12 as an expression
Step-by-step explanation:
To solve this problem, we need to distribute!
Multiply -3 by both the x and the 4
When we do this, we get:
-3x and -12
Note: when you multiply a positive by a negative, you get a negative so it turns into a negative number
Note 2: When you see an x without a number in front of it, it becomes 1x. In this problem, that is why it is a -3x because -3 x 1 is -3

Answer:
The ratio is 1/2 : 2.
The value of the ratio is 1/4.
The amount of salt in the recipe is 1/4 the amount of flour.
Step-by-step explanation:
The ratio of the salt to flour is the amount of salt and the amount of flour
1/2 cup salt and 2 cups flour would be 1/2 : 2 The value of a ratio is the ratio simplified (if we make the 1/2 a whole number we would multiply both sides of the ratio by 2 to get 1:4 or 1/4).
1/2 cup is a fourth of 2 cups
I'm not super familiar with ratio values but I'm pretty sure this is correct.

Answer:
B. b(a) = a/6 -9
Step-by-step explanation:
Solve the given equation for b.
a = 12(b +9)/2
a = 6(b +9) . . . . simplify
a/6 = b +9 . . . . divide by 6
a/6 -9 = b . . . . subtract 9
Then the inverse relation is ...
b(a) = a/6 -9 . . . . . . . matches choice B
A Tom bought these 3 t shirts at the sale price of $ 14. 50. How much money did he save compared to the original total of the t shirts B what percentage of the total price did Tom save
Answer:
$2.47
14.6%
Step-by-step explanation:
Total of the original prices:
$3.99 + $6.99 + $5.99 = $16.97
He paid $14.50 for the 3 shirts.
$16.97 - $14.50 = $2.47
He saved $2.47.
The percent he saved is
2.47/16.97 × 100% = 14.6%

What is the amplitude of the function shown in the graph?
Enter your answer in the box.
Answer:
1.5
Step-by-step explanation:
Amplitude: the height from the center line to the maximum or minimum point.
We can either determine the center line, or we can measure the height between the max to min points and divide that by 2.
From inspection of the graph, the max points are at y = -0.5 and the min points at y = -3.5
Therefore, the distance between them = -0.5 - -3.5 = 3
Divide by 2 = 3/2 = 1.5
Therefore, the amplitude = 1.5
(see attached graph for visual representation)

Answer:
20,000
Step-by-step explanation:
We can create a proportion to find the total budget. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the budget and percents.
\
Answer:
the company's total budget is 20,000
Step-by-step explanation:
A company spends 13% of its month budget on rent which total $2600
Let x be the month budget on rent
13% of the month budget is 2600
13% can be written as 13/100
Now we solve for x
multiply both sides by 100
divide both sides by 13
x=20000
So, the company's total budget is 20,000

Solve the following equation for y
Answer:

so you would subtract the 5x from both sides
-2y=10-5x
Two kindergarteners participated in a fundraiser event "Walk
Backwards for Hunger" last weekend. John walked 2/3 of a mile and Mary
walked 3/4 of a mile. Together, they raised $93.50. How much money, each, did
John and Mary raise? Just so you know, the amount raised is proportional to
distance walked
Answer:
John = $44 Mary = $49.50
Step-by-step explanation:
2/3 + 3/4 = 17/12
17/12x = 93.5
17/12x x 12 = 93.5 x 12
17x = 1122
17x/17 = 1122/17
x = 66
2/3x = 66 x 2/3
2/3x = 44
3/4x = 66 x 3/4
3/4x = 49.5
44 + 49.5 = 93.5
John earned $44 while Mary earned $49.5.
Sorry that the explanation was long, but I hope this helps! =D
The senior class of Oakdale Christian School traveled 630 miles in one day on their trip to the Grand Canyon. After lunch, they traveled twice as far as they did before lunch. How many miles did they travel after lunch?
Answer:
420 miles after lunch
Step-by-step explanation:
Day 1 is 630 miles travelled - total amount of travelling.
After lunch is twice the amount of m.
Twice means 2.
So,
2xm + m (they'd have travelled) = 630 total miles
(2xm = 2m & 1m is the same as m)
2m + 1m = 630
3m = 630
÷3
m = 210 miles
Initial miles travelled before lunch was 210.
After lunch is double that amount.
Thus, 210 x 2 = 420 miles
Check:
210 + 420 = 630 miles.
Hope this helps!
