Answer:
You would do the division first.
256 / 16 = 16
so, we have to determine 80 -16 +8
equals 72
Step-by-step explanation:
Answer:
The answer is 56
Step-by-step explanation:
To answer the equation, you must do the order of operations. Which is PEDMAS.
P= Parenthesis
E= Exponents and Radicals
M= Multiply
D= Divide
A= Add
S= Subtract
Always multiply, divide, add or subtract from left to right.
Because the equation is: 80 - 256 ÷ 16 + 8.
Your equation should be:
80 - 256 ÷ 16 + 8
= 80 - 16 + 8
= 80 - 24
= 56

An isosceles triangle in which the two equal sides, labeled a, are longer than the base, labeled b. This isosceles triangle has two sides of equal length, a, that are longer than the length of the base, b. The perimeter of the triangle is 15.7 centimeters. The equation 2a + b = 15.7 models this information. If one of the longer sides is 6.3 centimeters, which equation can be used to find the length of the base? 6.3+b=15.7 12.6+b=15.7 2a+6.3=15.7 2a+12.6=15.7
Answers
Hey There!!
The answer to this is: isosollese triangle has 2 equal sides that are longer than legnth of base
perimiter=15.7
equation is 2a+b=15.7
so if the longer side is 6.3, wat is legnth of base
we know that identical sides are bigger so 6.3 is one of the identical sides
2a means the 2 idneical sides
2(6.3)+b=15.7
12.6+b=15.7
subtract 12.6 from btohs ides
b=3.1
Thus, answer is base=3.1 cm

The blueprint scale is 1 inch : 9 feet if the gym's area is 60 square inches on the blueprint, what is the actual square footage of the gym
Answers
Answer:
4860 ft^2
Step-by-step explanation:
9 feet is represented by 1 inch.
● 9 => 1
Square both sides
● 81 => 1
So a 81 ft^2 square is represented by a 1 in^2 square (picture below)
■■■■■■■■■■■■■■■■■■■■■■■■■■
The gym's area in the blueprint is 60 in^2
That 60 1in^2 squares.
● 1 => 81
● 1×60 => 81×60
We have multiplied both sides by 60
● 60 => 4860
So the original are is 4860 ft^2
The actual square footage of the gym will be 4860 square feet.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.
There is no effect of dilation on the angle.
The blueprint scale is 1 inch : 9 feet.
Then the scale factor will be (1/9).
If the gym's area is 60 square inches on the blueprint.
Then the actual square footage of the gym will be
⇒ 60 / (scale factor)²
⇒ 60 / (1/9)²
⇒ 60 x 81
⇒ 4860 square feet
More about the dilation link is given below.

Step 1: m = StartFraction 4 minus (negative 2) Over 6 minus 3 EndFraction = StartFraction 6 Over 3 EndFraction = 2 Step 2: 3 = 2 (negative 2) + b Step 3: 3 = negative 4 + b. 7 = b. Step 4: y = 2 x + 7 Which best describes Terri’s first error? In step 1, the slope of the line should be One-half. In step 2, she should have substituted the point (4, 6). In step 3, she should have subtracted 4 from both sides of the equation. In step 4, the m and b values should be switched.
Answers
Answer:
(A) In step 1, the slope of the line should be One-half
Step-by-step explanation:
Terri calculated the slope as (x1 -x2)/(y1 -y2). Her first error was using this formula, when she should have used ...
m = (y1 -y2)/(x1 -x2)
= (6 -3)/(4 -(-2)) = 3/6 = 1/2
The best of the offered descriptions is ...
In step 1, the slope of the line should be One-half
Answer:
y = (1/2)x + 4
Step-by-step explanation:
As we move from the point (-2, 3) to the point (4, 6), x (the 'run') increases by 6 and y (the 'rise')increases by 3. Therefore the slope of the line connecting the two points is m = rise / run = 3/6, or m = 1/2.
We want the slope-intercept form of the equation of this line. The basic form is y = mx + b. Arbitrarily choosing to use the point (4, 6) and using m = 1/2, we get:
6 = (1/2)(4) + b, or b = 4.
Then the desired equation is y = mx + b, or y = (1/2)x + 4

Answers
Answer:
k = -1
Step-by-step explanation:
-3(k-8)-(k+5)=23
Distribute
-3k +24 -k-5 = 23
Combine like terms
-4k +19 = 23
Subtract 19 from each side
-4k +19-19 = 23-19
-4k = 4
Divide by -4
-4k/-4 = 4/-4
k = -1
Answer:
k = -1
Step-by-step explanation:
Use the distributive property to eliminate parentheses. That property tells you that the outside factor multiplies each term inside parentheses:
-3(k -8) -(k +5) = 23
-3k -3(-8) -k -(+5) = 23
-3k +24 -k -5 = 23 . . . . simplify
-4k +19 = 23 . . . . . . . . . collect terms
-4k = 4 . . . . . . . . . . . . . subtract 19 from both sides
k = -1 . . . . . . . . . . . . . . . divide both sides by -4

The rule for manipulating equations is, "any operation performed on one side of the equation must also be performed on the other side." Operations include addition, subtraction, multiplication, division, application of a function. Using the distributive property and collecting terms are ways to simplify equations that don't affect the truth of the equal sign (if those are done correctly).
In general, you make use of inverse operations to undo the operations you don't want. The goal is to get the variable by itself on one side of the equal sign.

Answer:
It is true.Step-by-step explanation:
It is example of "Distributive Law":
a × (b + c) = a × b + a × c
When we multiply a number by a group of numbers added together we get the same answer as when we do each multiply separately then add them.
Of course, if you don't remember the distributive law, you can verify it just by doing the operations on both sides of the equality:
(-50) × [37 + (-7) ] = (-50) × 37 + (-50) × (-7)
(-50) × [30] = (-1850) + 350

We can see that 2:9 =/= 2:12
Thus, the two are not equivalent ratios.
2. 5:20 and 15:60 are equivalent, 5:20 x 3 to both numbers is 15:60
Therefore, It is equivalent.
3. 17 times 4 is 68 and 3 times 4 is 12. 17:3 and 68:12 are equivalent because you can times and divide them into each other

can someone explain how to find the surface area to this composite figure.
Answers
Answer:
Surface Area= 498 cm²
Step-by-step explanation:
To calculate the surface area of this composite shape, work out the area of each face and add them together (break this composite figure into two shapes)
- Calculate the areas of the different sized faces
7 x 7 = 49
12 x 7 = 84
12 x 7 = 84
- Now, multiply these areas be number of corresponding faces
49 x 2 = 98
84 x 2 = 168
84 x 2 = 168
- Add these areas together
98 + 168 + 168 = 434
Now do the same for the shape above it
2 x 2 = 4 → 4 x 2 = 8
2 x 7 = 14 → 14 x 2 = 28
7 x 2 = 14 → 14 x 2 = 28 = 64
Add the surface areas together : 434 + 64 = 498 cm²

2(4x-3)-8=4+2x please solve this linear equation I need help
Answers
Answer:
x = 3
Step-by-step explanation:
Perform the indicated multiplication. We get
8x - 6 - 8 = 4 + 2x
Combining the x terms results in:
6x - 14 = 4
Isolate x by adding 14 to both sides:
6x = 18
Find x by dividing both sides by 6:
x = 18/6 = 3
x = 3
The solution or the value of x for the given linear equation 2(4x-3)-8=4+2x is x = 3.
Given that:
2(4x - 3) - 8 = 4 + 2x
Use the distributive property on the left-hand side.
(2 × 4x - 2 × 3) - 8 = 4 + 2x
(8x - 6) - 8 = 4 + 2x
Using the associative property:
8x + (-6 - 8) = 4 + 2x
8x - 14 = 4 + 2x
Subtract both sides by 2x.
8x - 2x - 14 = 4
6x - 14 = 4
Add 14 on both sides.
6x = 18
Divide both sides by 6.
x = 3
Hence, the value of x is 3.
