Carlos is a member of a gym. He pays a monthly fee plus a per- visit fee. The equation y = 3x + 10 represents the monthly amount Carlos pays for x visits.
if Carlos pays $85 in the last month how many times did he visit the gym?
Answers
Answer:
25 times
Step-by-step explanation:
To find how many times he visited, plug in 85 as y and solve for x:
y = 3x + 10
85 = 3x + 10
75 = 3x
25 = x
So, Carlos visited the gym 25 times

"7x^2+19x-6 = 0
Answers
Step-by-step explanation:
Given
7x² + 19x - 6 = 0
7x² + (21 - 2) x - 6 = 0
7x² + 21x - 2x - 6 = 0
7x( x + 3 ) - 2 ( x + 3 ) = 0
(x + 3 ) ( 7x - 2 ) = 0
Either
x + 3 = 0
x = - 3
Or,
7x - 2 = 0
7x = 2
x = 2 /7
So
x = - 3 and 2/7
Hope it will help :)
Answer:
x= -3,/2/7
Step-by-step explanation:
split the second term in 7x^2 + 19x-6 into two terms 7x^2+21x-2x-6=0
Factor out common terms in the first two terms7x(x+3)-2(x+3)=0
(x+3)(7x-2)=0
Factor out the common term x+3 hope that help x= -3,/2/7

Answers
Answer:
8[tex]x^{2}[/tex] + 3 + -6x
Step-by-step explanation:
First we need to find the like terms so that we could add them. In this case the like terms are,
1. 6x , -2x , -10x
So, these are the only terms that we can add in this expression.
Hence,
=> 8[tex]x^{2}[/tex] + 3 + (6x - 2x - 10x)
=> 8[tex]x^{2}[/tex] + 3 + -6x
And this is as simple as this expression can go until we find the value of "x" which is not yet told.

the event and the ratio of adults to children was 7:9.
a.
Work out the total revenue from ticket sales
b.
60% of the tickets cost was given to charity.
How much was given to charity?
Answers
Answer:
Total revenue = $13,250
Amount given for charity = $7,950
Step-by-step explanation:
Children = $10
Adults = $25
Total people = 800
ratio of adults to children was 7:9.
Total ratio = 7 + 9 = 16
Adults = 7/16 × 800
= 0.4375 × 800
= 350
Adults = 350
Children = 9/16 × 800
= 0.5625 × 800
= 450
Children = 450
Total revenue = ($10 × 450) + ($25 × 350)
= $4,500 + $8,750
= $13,250
Total revenue = $13,250
60% of the tickets cost was given to charity.
Amount given for charity = 69% of $13,250
= 0.60 × $13,250
= $7,950
Amount given for charity = $7,950

6.28 + 24 + 3 + 2 = 35.28 sq. units
Step-by-step explanation:
The screenshot is how I split it. (A semicircle with a radius of 2, a trapezoid (base a: 5, base b: 7, height 4), and two triangles (b1: 3, h1: 2; b2: 4, h2: 1)
To find the area of a semicircle, use the formula πr²/2. I'll use 3.14 for pi.
3.14(2²)/2
Square 2 to get 4.
3.14(4)/2
Multiply 3.14 by 4 to get 12.56.
12.56/2
Divide 12.56 by 2 to get 6.28
The semicircle is 6.28 units².
To find the area of a trapezoid, use the formula (a+b)h/2.
(5 + 7) * 4/2
Add 5 and 7 to get 12.
(12 * 4)/2
Multiply 12 by 4 to get 48.
48/2
Divide 48 by 2 to get 24.
The trapezoid is 24 units².
For the triangles, simply use this: bh/2
3 * 2 / 2
The 2's cancel out, so you're simply left with the first triangle being 3 units².
4 * 1 / 2
This really just becomes 4/2 as 4 * 1 is just 4.
4/2
Divide 4 by 2 to get 2.
The second triangle is 2 units².
Now that we know the areas of the four figures, add them together.
6.28 + 24 + 3 + 2
6.28 + 27 + 2
6.28 + 29
The area of the figure is 35.28 units².
