Answer:
1. x=6
2. x=9
Step-by-step explanation:
1.
[tex]-2(3x+9)=-54\\-6x-18=-54\\+18 +18\\-6x=-36\\\frac{-6x}{-6} = \frac{-36}{-6}\\x=6[/tex]
2.
[tex]2(3x+4)-3x=35\\6x+8-3x=35\\3x+8=35\\-8 -8\\3x=27\\\frac{3x}{3} =\frac{27}{3} \\x=9[/tex]
Written Explanation:
1.
-2x(3x+9)=-54
-6x-`8=54 (Distributive property)
Add 18 to both sides
-6x=-36
Divide both sides by -6 (negative divided by a negative equals a positive)
x=6
2.
2(3x+4)-3x=35
6x+8-3x=35 (distributive property)
3x+8=35 (combine Iike terms and then subtract them 6x-3x=3x)
Subtract 8 from both sides
3x=27
Divide both sides by 3
x=9

Step-by-step explanation:
Camilla, Lincoln and Ella sat a French test. The test was marked out of 200
Camilla got 4/5 of the 200 marks.
Lincoln got 44% of the 200 marks.
Ella got 198 out of 200 marks.
Who got the highest mark?
Answer:
Ella got the highest marks.
Step-by-step explanation:
Given that:
Camilla got 4/5 of the 200 marks.
Marks of Camilla = [tex]\frac{4}{5}*200[/tex]
Marks of Camilla = 160 marks
Lincoln got 44% of the 200 marks.
Marks of Lincoln = [tex]\frac{44}{100}*200[/tex]
Marks of Lincoln = 88 marks
Ella got 198 out of 200.
On comparing,
198 is the highest out of 200.
Hence,
Ella got the highest marks.

True or False: (1, 3) is a solution to the system of linear equations shown
below.
y= 4x - 1
y = x + 2
Answer:
True
Step-by-step explanation:
(1, 3) is a solution to the system of linear equations shown is true
Answer:
True
Step-by-step explanation:
You can substitute x = 1 and y = 3 into both equations and see if it's true or not.
y = 4x - 1
becomes
3 = 4(1) - 1
3 = 4 - 1
3 = 3
True
y = x + 2
becomes
3 = 1 + 2
3 = 3
True
Since both equations come out true, this (1, 3) is a solution.

Please help! Lynda has $32.00 to spend at the grocery store on boxes of macaroni and cheese. The cost is $3 per box. In addition, her mom told her to buy some oranges that will cost $5. Which equation will let Lynda know how many total boxes of macaroni and cheese,m, she can buy?
A.32 = 5m + 3
B.32 = 3m + 5
C.32 = 3(m - 2) - 5
D.32 = 3(m - 2) + 5
Answer:
B
Step-by-step explanation:
So first we subtract 5 from 32. Then we use that number ÷ 3, and that's the answer. As for the question, We can rule our A because its 3 per box and not 5, and the whole (m-2) thing makes no sense because there isnt a 2 anywhere. I hope this helps!
The equation 32 = 3m - 5 will let Lynda know how many total boxes of macaroni and cheese, m, she can buy.
What is linear equation?Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.
Given:
Lynda has $32.00 to spend at the grocery store on boxes of macaroni and cheese.
The cost is $3 per box.
If the boxes are m, then the total cost = 3m.
In addition,
her mom told her to buy some oranges that will cost $5.
That means, the linear equation,
32 = 3m - 5
Therefore, the equation is 32 = 3m - 5.

Answer:
Jamie will need 6 cups of milk.
Step-by-step explanation:
Given that:
A recipe calls for 2 cups of milk for each batch of pancakes.
1 batch of pancakes = 2 cups of milk
As Jamie is going to triple her recipe, thus the amount of milk in the recipe will also be tripled.
3 batches of pancakes = 2*3 cups of milk
3 batches = 6 cups of milk
Hence,
Jamie will need 6 cups of milk.

What is the value of (33 - 2 × 7) + (5 × 3 - 22) ?
Answer:
12
Step-by-step explanation:
Keep in mind the rules of PEMDAS
P (parenthesis)
E (exponents)
M (multiply)
D (division)
A (addition)
S (subtraction)
Because parenthesis is the first operation in PEMDAS, you would start by calculating inside the parenthesis
We can start with the numbers inside the first parenthesis
(33 - 2 × 7)
Start by multiplying 2 and 7 because the M comes before the S
(33 - 2×7)= (33- 14)
Now subtract 14 from 33
(33-14) = 19
Step 2: Calculate inside the second parenthesis
(5 × 3 - 22)
Multiply first
(5 × 3 - 22)= (15 - 22)
Subtract!
(15 - 22)= -7
Now add the final number together
(why? There is an addition sign between the two parenthesis ordering us to add the final numbers together)
19 + (-7)
19-7

Solve 4(t+1)= 6(g-4)
Answer:
Step-by-step explanation:
Simplifying
4(t + 1) = 6(g + -4)
Reorder the terms:
4(1 + t) = 6(g + -4)
(1 * 4 + t * 4) = 6(g + -4)
(4 + 4t) = 6(g + -4)
Reorder the terms:
4 + 4t = 6(-4 + g)
4 + 4t = (-4 * 6 + g * 6)
4 + 4t = (-24 + 6g)
Solving
4 + 4t = -24 + 6g
Solving for variable 't'.
Move all terms containing t to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + -4 + 4t = -24 + -4 + 6g
Combine like terms: 4 + -4 = 0
0 + 4t = -24 + -4 + 6g
4t = -24 + -4 + 6g
Combine like terms: -24 + -4 = -28
4t = -28 + 6g
Divide each side by '4'.
t = -7 + 1.5g
Simplifying
t = -7 + 1.5g
