what is the soution to following equation: 1/2(x-10)=3/4(x+8)
Answer: x = -44
Step-by-step explanation:
1/2(x - 10) = [tex]\frac{3}{4}[/tex] (x+8) Apply the distributive property
1/2x - 5 = 3/4x + 6 Add 5 to both sides
+5 +5
1/2x = 3/4x + 11 Subtract 3/4x from both sides
-3/4x -3/4x
-1/4x = 11 Divide both sides by -1/4
x = -44
0.2(x + 3) - 4(2x - 3) = 3.4

x= 1.¯17948¯¯
Explain:
Isolate the variable by dividing each side by factors that don't contain the variable
Answer:
your answer is incorrect
Step-by-step explanation:
0.2 times (x+3) = 0.2x + .6
4(2x-3) = 4 x 2x + 4 x -3 = 4 x 2x + -7 = 6x + -7
0.2x + .6 - 6x + -7 = -5.8x + -7
because you cannot combine terms that are not alike, then your final answer would have to be -5.8x + -7 because you did not give us what x is equal to.
Which is the correct simplified version of the expression shown below
after combining like terms?
12 + 3.4x -5.4x - X
A. -3x + 12
B. 9x
C. 9.8x + 12
D. -2x + 12
Answer:
D. -2x+12
Step-by-step explanation:
you combine all values with x because they are like terms.
:) hope this helps
Answer:
-2x+12
D is the best answer.

f(x)=22x+14, find f(5)
Answer:
f(5) = 124
Step-by-step explanation:
Step 1: Define
f(x) = 22x + 14
f(5) = x = 5

What is the solution of 6x= 15
Answer:
2.5
Step-by-step explanation:
When a variable is next to a number (coefficient) it means you need to multiply. In this equation 6x are next to eachother.
Because we don't know what x is, we have to work backwards.
The opposite of multiplying is dividing, so here we can do...
15/6 and that equals 2.5
To check you replace x with 2.5 like so,
6(2.5)= 15 and it is true!
Hope this helps and have a great day!

If y=4x + 5,
What is y when Ox= 3, and ii) x= -3
When x= 3 then y= 17
When x = -3 then y = -7
6y + 9 = 33 solve for y
Answer:
-3.5
Step-by-step explanation: 33/6= 5.5 5.5-9= -3.5
Answer:
y = 3
Step-by-step explanation:
1. Subtract 33 by 15 (9+6)
2. You get the answer 18
3. 6 times y = 18
4. y = 3 ; therefore y equals 3.
5. Y = 3
HELP I WILL MARK YOU BRAINLIEST A bag of flour contains 5 pounds of flour. A batch of cookies required 0.10 pounds of flour. How many batches can be made with the 5-pound bag?
Answer:
50 batches
Step-by-step explanation:
A bag of flour = 5 pounds of flour
A batch of cookies = 0.10 pounds of flour
How many batches can be made with the 5-pound bag?
Batch of cookies in 5 pounds of flour = Total pounds of flour / flour needed per batch of cookies
= 5 pounds / 0.10 pounds
= 50 batches of cookies
50 batches of cookies can be made with 5 pounds of flour

A group of 6 hikers are preparing for a one week trip. All of the group's supplies will be carried by the hikers in
backpacks. The leader decides that each hiker will carry a backpack that is the same fraction of weight to all the other
hikers' weights. This means that the heaviest hiker would carry the heaviest load. The table below shows the weight of
each hiker and the weight of the backpack
Complete the table. Find the missing, amounts of weighit by applying the same value of the ratio as the first two rows.
Backpack Weight
Hiker's Weight
152 15.402
Total Weight (lb.)
14 1b, 802
107 lb, 10 oz
10 lb. 4 02
129 lb. 15 02
68 10.40
8 lb. 12 oz
10 lb
Answer:
Step-by-step explanation:
1 oz = 0.0625 lb
Ratio of the hiker an backpack in the first row = 152.25 lb : 14.5 lb
= 21 : 2
Hiker's weight Backpack weight Total weight (in lb)
1). 152 lb 4 oz 14 lb 8 oz (152+14) lb (4+8) oz = 164lb 12oz
= 16.75 lb
2). 107 lb 10 oz 10 lb 4 oz (107+10) lb (10+4) oz = 117 lb 14 oz
= 117.875 lb
3). 129 lb 15 oz [tex]\frac{129.9375}{x}=\frac{21}{2}[/tex] (129+12) lb (15+6)oz = 141 lb 21 oz
x = 12.375 lb = 142.3125lb
x = 12 lb 6 oz
4). [tex]\frac{x}{8.75}=\frac{21}{2}[/tex] 8 lb 12 oz (8 + 91) lb (14+12) oz = 99 lb 26 lb
x = 91.875 lb = 100.625 lb
x = 91 lb 14 oz
5). [tex]\frac{x}{10}=\frac{21}{2}[/tex] 10 lb (105 + 10) lb = 115 lb
x = 105 lb
