The length of each of the two congruent sides of an isosceles triangle is 3x - 1. The length of the third side is 2x + 1. The perimeter is 55 feet. Which equation does NOT represent the perimeter?
8x - 1 = 55
6x - 2 + 2x + 1 = 55
2 (3x - 1 + 2x + 1) = 55
2 (3x - 1) + (2x + 1) = 55
Answers
Explanation:
This equation does not represent the perimeter.
To write the equation:
2(3x - 1) + (2x + 1) = 55
6x - 2 + 2x + 1 = 55
8x - 1 = 55
Thus, 3 of the choice represent but the the third choice didn’t appear in the equation.

Step-by-step explanation:
what is the y-intercept of (5,8) and (12,36)
Answers
Answer:
The y intercept is (0,-12)
Step-by-step explanation:
You use the slope formula and the slope-intercept form to find the slope m and then the y intercept b.
Answer:
(0, -12)
Step-by-step explanation:
In order to find the y-intercept of the equation y = mx + b ( where m is the slope and b is the y-intercept), we first have to find the slope. We can do this by using the two points given to us.
To find the slope:
The slope is equal to: [tex]\frac{y2 - y1}{x2 - x1}[/tex]
Let's plug (5,8) and (12,36) into the equation:
[tex]\frac{36 - 8}{12 - 5}[/tex]
Now let's solve for the slope:
36 -8 = 28
12 - 5 = 7
So we get: [tex]\frac{28}{7}[/tex]
Now that we've found the value of the slope, we can put it into the equation:
y = [tex]\frac{28}{7}[/tex]x + b
To find the value of b, we can input the values of one of the given points into the equation and solve for b. Let's use (5,8):
Input the values of x and y into the equation: 8 = [tex]\frac{28}{7}[/tex](5) + b
Multiple [tex]\frac{28}{7}[/tex] by 5: 8 = [tex]\frac{140}{7}[/tex] + b
Divide 140 by 7: 8 = 20 + b
Subtract 20 from both sides of the equation to isolate b:
8 - 20 = 20 - 20 + b
-12 = b
The y-intercept is (0, -12).
Milan
putting money into a savings account. He starts with $350 in the savings account, and each week he adds $60.
Let S represent the total amount of money in the savings account (in dollars), and let W represent the number of weeks Milan has been adding money. Write an
equation relating S to W. Then use this equation to find the total amount of money in the savings account after 17 weeks.
Answers
Answer:
Milan will have $1,370 in the account after 17 weeks.
Step-by-step explanation:
S(W) = 350 + 60W
S(17) = 350 + 60*70 = 1370
y=sxw+n
y= 350xw+60

what is the value of x for the equation: x/3+x=x/6-1
Answers
6x/3x = 2x
2x + x = 3x
3x = -1
x = -1/3
Answer:
I think the answer may be
X=2
Step-by-step explanation:
x÷3+x=x÷6-1
Add the common factors together to get
2x÷3=x÷6-1
subtract on the right side to get
2x÷3=x÷5
subtract 3 from both sides to get
2x=x÷2
subtract x from both sides to get
1x=2

Nick is given $50 on a vacation. He decides to spend $5 a day. Write an equation relating to the amount of money Nick has left, y, and the number of days, x, Nick spends money
Answers
Answer:
y = -5x + 50
Step-by-step explanation:
We'll write the equation in y = mx + b form, where b is the original amount of money (50), and m is the amount of money he spends he each day(5). Since he's spending 5 dollars, that means that 5 dollars is being lost everyday, so m will be -5:
y = -5x + 50

Step-by-step explanation:
So first off, let's find the other side.
651 divided by 7 = 93
93 would be the other side measurement. There are two sides that measure 93 degrees, two sides that measure 7 degrees.
93 + 93 + 7 +7 = perimeter

a waterslide has an angle of elevation of 20 degrees whats is the rise for a run of 2.6 m?
Answers
Answer:
Therefore, the rise will be 0.95 m
Step-by-step explanation:
As the waterslide has an angle of elevation of 20 degrees.
Ф = 20°
And we have to determine the rise for a run of 2.6 m.
All we need is to use the trigonometric ratio of tan Ф
Because
tan Ф = rise/runAs
run = 2.6 m
Ф = 20°
so
tan Ф = rise/run
tan (20) = rise/run
rise = tan (20) × 2.6
rise = 0.95 m
Therefore, the rise will be 0.95 m
