Answer:
-10x+2+x=-4x+12
-9x+2=-4x+12
-9x+4x+2=12
-9x+4x=12-2
-5x=10
x=-2
Step-by-step explanation:
Answer:
x= -2
Step-by-step explanation:
-2(5x-1)+x=-4(x-3)
Now, use distributive property on both sides
-10x+2+x = -4x+12
Simplify
-9x+2= -4x+12
-5x= 10
x=-2

Answer:
See below
Step-by-step explanation:
Well, we know the scale is 1 1/2 inches to 4 feet and that one side length of the scaled drawing sqaure is 3 inches, so . . .
3/1 1/2 (3 divided by one and one-half)
to get: 2
Then multiply it by the scale factor of 4
2*4= 8
But remeber, this is only ONE side of the garden, so multiply this by 4
8*4=32
Next we want to see the number of links it takes to build the garden
Since one link measures 2 2/3 feet you have to divide
32/ 2 2/3 (32 divided by two and two-thirds)
to get an answer of : 12 links
A certain bacterium splits itself into 2 identical cells in 1 day. Each of those new cells is capable of splitting itself into 2 identical cells in 1 day. So the first day there are 2 cells, the second day there are 2 x 2 cells, and so on. Write and evaluate an expression using a base and an exponent to represent the number of cells present at the end of the 7th day.
Answer:
2 with the second power??
Step-by-step explanation:
if you have two with the second power II exponents will multiply it by itself so the number gradually gets larger each time

You made Marcellus 3 times as tall as Dan but you dragged Marcellus’s eyes to be 1 times as far apart as Dan’s eyes. A scale giant would have the same multiple for both.
If Dan's eyes are 5 cm apart, how many centimeters apart should Marcellus's eyes be?
Marcellus's eyes should be 5 cm apart
If Marcellus eyes are 1 times as far apart as Daniels eyes. We can write this mathematically as;
Marcellus eyes are 1x far apart as Dan's eyes.
If we spin this over, we are told that Dan's eyes is 5 cm apart. How far apart would Marcellus's be.
Marcellus eyes will be Dan's eyes divided by the mathematical equivalent we wrote the other time, which is 1 times.
Essentially, Marcellus's eyes will be just as wide as Dan's eyes

Answer:
8 : 20 and 24 : 60
Step-by-step explanation:
Given the ratio
[tex]\frac{2}{5}[/tex]
To obtain a ratio with 20 on the denominator multiply numerator and denominator by 4
= [tex]\frac{2(4)}{5(4)}[/tex] = [tex]\frac{8}{20}[/tex]
To obtain a ratio with 24 on the numerator multiply numerator and denominator by 12
= [tex]\frac{2(12)}{5(12)}[/tex] = [tex]\frac{24}{60}[/tex]

Answer:
∠ ABC = 87°
Step-by-step explanation:
∠ ABD and ∠ DBE are adjacent angles and are supplementary, sum to 180° , so
2x - 17 + x + 32 = 180 , that is
3x + 15 = 180 ( subtract 15 from both sides )
3x = 165 ( divide both sides by 3 )
x = 55
Then
∠ DBE = x + 32 = 55 + 32 = 87° , thus
∠ ABC = ∠ DBE ( vertical angles )
∠ ABC = 87°

5 Solve for x. 8 = 2x + 4
Answer:
8 = 2x + 4collect like terms8 - 4 = 2x4 = 2xdivide both sides by 24/2 = 2x/2X = 2Answer:
x=2 (answer should have a positive sign.)Step-by-step explanation:
To solve this problem, you have to isolate the x from one side of the equation.
First, switch sides.
8=2x+4
2x+4=8
Subtract by 4 from both sides.
2x+4-4=8-4
Solve.
8-4=4
2x=4
Then, divide by 2 from both sides.
2x/2=4/2
Solve.
4/2=2
x=2
The solution is 2.

Answer:
If you used π, 157.079632679 yards or 157.08 yards rounded to the hundredths place. If you used 3.14, the answer is 157 yards.
Step-by-step explanation:
The formula to find the perimeter of a circle is P=2×π×r.
Step 1: Find the radius. In this case, the radius is 25 yards as shown in the diagram.
Step 2: Since the formula only includes multiplication, you can multiply any of the factors. For simplicity, multiply your radius by 2 first. In this case, 2×25=50.
Step 3: Multiply your last number with π. In this case, 50×π=157.079632679 or 157.08 rounded the hundredths place. 50×3.14=157.
Step 4: You found the answer! Hope this helps.
