Step-by-step explanation:
2x + 3x + 4x = 180
9x = 180
x = 20
2x = 2(20)=40
3x = 3(20)=60
4x = 4(20)=80

What is the equation of the line that passes through the point (4,−7) and has a slope of -1/2?
Step-by-step explanation:
y = -0.5x + c
When x = 4, y = -7.
=> (-7) = -0.5(4) + c, c = -5.
Therefore the equation is y = -0.5x - 5.
Answer:
y = -1/2 x - 5
Step-by-step explanation:
y = mx + b
m = slope = -1/2
y = -1/2 x + b
-7 = -1/2 * 4 + b
-7 = -2 + b
b = -5
y = -1/2 x - 5

Alani is the head baker at Patty Cakes Bakery.
She uses 8.75 pounds of sugar each day making
cupcakes. How many pounds of sugar would she
use over 7 days?
1. After the cupcakes are decorated, Alani packages
them to be sold. Each cupcake costs $4.25. If a
customer ordered 9 cupcakes, how much would
it cost?
ANSWER BOTH QUESTIONS AND WHOEVER DOES IT FIST GETS BRAINIEST
Answer:
1).Sugar used in 7 days = 61.25 pounds
2). Total cost of 9 cupcakes = $38.25
Step-by-step explanation:
1). Alani uses 8.75 pounds of sugar each day.
So, sugar used in 7 days = Amount of sugar used in one day × Number of days
= 8.75 × 7
= 61.25 pounds
2). Since, each cupcake costs $4.25
Number of cakes ordered = 9
Total cost of 9 cupcakes = Cost of each cupcake × Number of cupcakes
= 4.25 × 9
= $38.25

-4(2-5b)=132
whats b?
Answer:
b = 7
Step-by-step explanation:
- 4(2 - 5b) = 132
- 4 × 2 - 4 × (- 5b) = 132
-8 + 20b = 132
20b = 132 + 8
20b = 140
b = 140/20
b = 7
Thus, The value of b is 7

Step-by-step explanation: The opposite of Multipication is division so divide 84 by 12
Answer:
k=7
Step-by-step explanation:
Call me weird but I love these types of questions.
Ok to solve this here's what you need to do.
Your solving for k right?
So make an equation.
Product is the result of multiplication so 12 and k would be 12k.
It needs to equal 84 so 12k=84
Now you need to get rid of 12.
You need to use the opposite operation as the number your trying to get rid of. In this case it would be division.
[you do not divide the x because you need it alone on one side]
So 12k divided by 12 = 84 divided by 12
12k/12 is k because a number divided by itself is 1.
84/12 is 7.
that leaves us with k=7
Thats it!

Samuel bought 4 rolls of tape to seal boxes. Each roll contains 32.9 meters of tape. He uses 1 1/5 meters of this tape to seal each box. What is the total number of boxes Samuel can seal with these 4 rolls of tape?
Answer:
109.33 boxes
Step-by-step explanation:
The first step is to calculate the total number of tape
= 32.9 × 4
= 131.6 m
Therefore the total number of boxes that Samuel will use to seal the boxes can be calculated as follows
= 131.6/ 1 1/5
= 131.6 ÷ 6/5
= 131.6 × 5/6
= 658/6
= 109.33 boxes

the coffee pub has cans of coffee that weigh 3 1/4 pounds each. the pub has 8 1/2 cans of coffee left. what is the total weight of 8 1/2 cans ? show your work
Final Answer: [tex]27\frac{5}{8}[/tex] pounds
Final Answer Reason: The total weight of [tex]8\frac{1}{2}[/tex] cans would be [tex]27\frac{5}{8}[/tex] pounds
Steps/Reasons/Explanation:
We'll need to find the total weight of [tex]8\frac{1}{2}[/tex] cans, so we would need to multiply [tex]3\frac{1}{4}[/tex] cans by [tex]8\frac{1}{2}[/tex] cans. We are solving for the total weight of [tex]8\frac{1}{2}[/tex] cans.
Question: The coffee pub has cans of coffee that weigh [tex]3\frac{1}{4}[/tex] pounds each. The pub has [tex]8\frac{1}{2}[/tex] cans of coffee left. What is the total weight of [tex]8\frac{1}{2}[/tex] cans?
Solve For: The total weight of [tex]8\frac{1}{2}[/tex] cans.
Steps: Multiply to find total weight of [tex]8\frac{1}{2}[/tex] cans.
[tex]3\frac{1}{4}[/tex] × [tex]8\frac{1}{2}[/tex]

Given that triangle RST is isosceles, find the value of ZS
Answer:
120°
Step-by-step explanation:
[tex]m\angle S = 180\degree - 2\times 30\degree \\\\
m\angle S = 180\degree - 60\degree \\\\
\huge\purple {\boxed{m\angle S = 120\degree}} [/tex]
1) LaTeX: m\angle1=\:\:\:\:\:\:\:\:^\circm ∠ 1 = ∘
2) LaTeX: m\angle2=\:\:\:\:\:^\circm ∠ 2 = ∘
3) LaTeX: x\:=\:\:\:\:m\:\left(exterior\:angle\right)\:=
Answer:
1. m<1 = 139°
2. m<2 = 41°
3. x = 29
Step-by-step explanation:
1. m<1 = 86° + 53° (exterior angle theorem of a triangle)
m<1 = 139°
2. 133° = m<2 + 92° (exterior angle theorem of a triangle)
133° - 92° = m<2 (Subtraction property of equality)
41° = m<2
m<2 = 41°
3. 4x + 15 = 93° + (x + 9)° (exterior angle theorem of a triangle)
Add like terms
4x + 15 = 102 + x
4x - x + 15 = 102 (substraction property of equality)
3x + 15 = 102
3x = 102 - 15
3x = 87
x = 87/3 (division property of equality)
x = 29
