2r +8= 26
» What is the value of r?
meters
Answer:
r = 9 meters
Step-by-step explanation:
2r + 8 = 26 <== subtract 8 from both sides
- 8 - 8
2r = 18 <== divide both sides by 2 to isolate the variable
/2 /2
r = 9 meters
Hope this helps!
Answer:
[tex]\boxed{\sf{r=9}}[/tex]Step-by-step explanation:
To find the value of r, isolate it on one side of the equation.
[tex]\sf{2r+8=26}[/tex]
First, you have to subtract by 8 from both sides.
[tex]\sf{2r+8-8=26-8}[/tex]
Solve.
Subtract the numbers from left to right.
26-8=18
2r=18
Divide by 2 from both sides.
[tex]\sf{\dfrac{2r}{2}=\dfrac{18}{2} }[/tex]
Solve.
Divide the numbers from left to right.
18/2=9
r=9
Therefore, the correct answer is r=9 meters.I hope this helps. Let me know if you have any questions.

Which term of the AP 2,8,14,20..... Will be 210 more than it's 60th term?
Answer:
95th term
Step-by-step explanation:
the nth term of an AP is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 2 and d = a₂ - a₁ = 8 - 2 = 6 , then
[tex]a_{n}[/tex] = 2 + 6(n - 1) = 2 + 6n - 6 = 6n - 4
the 60th term is then
a₆₀ = 6(60) - 4 = 360 - 4 = 356
so 210 more than a₆₀ = 356 + 210 = 566
now equate [tex]a_{n}[/tex] to 566 and solve for n
6n - 4 = 566 ( add 4 to both sides )
6n = 570 ( divide both sides by 6 )
n = 95
Answer:
95th term.
Step-by-step explanation:
The sequence of 2, 8, 14, 20 . . . can be predicted by adding 6 to each successive term. This can be written as 6n+2, where n starts at 0 for the first term.
n Value (6n+2)
0 2
1 8
2 14
3 20
4 26
60 362
---
We want to know what term is 210 more than 362. (362+ 210) = 572
We can solve by using the equation in reverse and solving for n:
(6n+2) = 572
6n = 570
n = 95
The 95th term (572) is greater than the 60th term (362) by 210.
If carol travels 4 miles and her car averages 28 miles per hour, how long will it take carol to complete the distance? Express this situation in an equation, making t the variable of time
Answer: t= Distance/Speed = 4/28= 1/7
Step-by-step explanation:
Speed is 28miles /hr
Distance = 4miles
Distance = Speed × time
Time(t) = Distance /Speed
Farrah borrowed $155 from her brother. She has already paid back $15. She plans to pay back $35 each month until the debt is paid off.
Which describes the number of months it will take to pay off the debt? Select three options.
x + 15 + 35 = 155
35 x + 15 = 155
35 x = 155 minus 15
It will take 8 months to pay off the debt.

D Line t has a variable slope.
The rise/run of AC and CE in the similar triangles are the same, the true statement is: B. slope of AC = slope of CE.
What is the Slope of the Sides of Similar Triangles?On a coordinate plane, the corresponding sides of two triangles are always the same because the ratio of the rise over run is always the same.
Triangles ABC and CDE are similar triangles, therefore the rise over run of AC and CE, which is the slope, will be the same.
Thus, slope of AC = slope of CE.

Answer:
B & C
Step-by-step explanation:
Acute angles are sharp-like angle - they are measured between 1° up to 89°. That means acute angles have measurement starting from 1 to 89.
The shape of acute angles, as said, they are namely sharp angles because their vertex and lines form sharp shape.
So what you have to do is to find angles that look like a sharp pencil/pen, probably something that can be understandable:
Sharp-looking measurements are:
∠DBA∠GFEKeep in mind that ∠GFE is really an acute angle, but ∠HFE is a right angle.
Let’s look into more types of angles as shown in choices:
∠DBC is an obtuse angle - it is the angle measurement between 91° up to 179°∠MLK is a right angle - it is the angle measurement of exact 90° - keep in mind, only right angles can have measurement of 90°Hence, acute angles are ∠GFE and ∠DBA
The angles which are acute are ∠GFE and ∠DBA.
What are Angles?Angles are the figure formed by the intersection of two lines or rays by sharing a common point. This point is called the vertex of the angle.
Angles are usually measured in degrees or radians.
Given three figures and corresponding angles.
We have to find the acute angles.
Acute angles are angles which measures less than 90 degrees.
An angle which measure 90 degrees is the right angle which stands vertically.
Acute angles are less than this.
From the figure and options, acute angles are ∠GFE and ∠DBA.
Hence the acute angles are ∠GFE and ∠DBA.

a car uses 9 gallons of gasoline to go 162 miles. how many gallons of gasoline will the same car use to travel 216 miles?
Answer:
[tex]12\ gallons[/tex]
Step-by-step explanation:
Step 1: Determine the unit rate
[tex]Miles / Gallons[/tex]
[tex]162\ miles / 9\ gallons[/tex]
[tex]18\ miles/gallon[/tex]
Step 2: Determine the amount of gasoline used for 216 miles

[tex]12\ gallons[/tex]
Answer: [tex]12\ gallons[/tex]
Answer:
12
Step-by-step explanation:
1. Figure out how many miles the car can go with one gallon of gasolline
162 ÷ 9 = 18
1 gallon = 18 miles
2. Figure out how many times 18 can go into 216
216 ÷ 18 = 12
12 gallons = 216 miles
*We do this because we know that every time the car drives 18 miles its uses another gallon of gas.
The car will use 12 gallons of gasoline to travel 216 miles.
