Answer:
choice 1) 2x + 40 = 180
Step-by-step explanation:
(x + 10) + (x + 30) = 180
2x+ 40 = 180
Answer:
X+30+x+10=180
combine like terms
2x+40=180
subtract 40 from both sides
2x=140
divide by 2
x=70
but for you it is 2x+40=180

Given the function ƒ(x) = 3x + 5, find ƒ(4) and x such that ƒ(x) = 38.
Answer:
just plug 4 inside f(x)=3(4)+5
3x+5=38
3x=33
Divid by 3 on both sides
x=11

Leo is 13 3 4 years old. Sheila is 1 1 2 years older than Leo and Jane is 1 1 5 years older than Sheila. How old is Jane?
Answer:
16 9/20 years old
Step-by-step explanation:
Leo is 13 3/ 4 years old.
Step 1
Sheila is 1 1 /2 years older than Leo
Sheila = 13 3/4 years + 1 1/2 years
13 + 1 + ( 3/4 + 1/2)
Lowest common denominator 4
14 + ( 3 + 2/4)
14 + 5/4
= 14 + 1 1/4
= 15 1/4 years old
Jane is 1 1/ 5 years older than Sheila.
Jane's age = 15 1/4 years old + 1 1/5 years
15 + 1 + (1/4 + 1/5)
Lowest common denominator = 20
16 + (5 + 4/20)
16 9/20 years old
Therefore, Jane is 16 9/20 years old

Write an equation in slope-intercept form given the information about each line.
10. slope = 4, goes through the point (3, 10)
Answer:
y = 4x - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 4 , then
y = 4x + c ← is the partial equation
To find c substitute (3, 10) into the partial equation
10 = 12 + c ⇒ c = 10 - 12 = - 2
y = 4x - 2 ← equation of line

A sandwich store charges $20 to have 3 turkey subs delivered and $26 to have 4 delivered. The total includes the cost of each sub, plus the delivery fee.
Answer:
cost of each sub = $6, delivery fee = $2

Let $x be the cost of each sub and $c be the delivery fee
3x + c = 20
4x + c = 26
x = 6, c = 2

A soup bowl is in the shape of a hemisphere with a diameter of 10 cm. What is the approximate maximum volume of soup that the bowl can hold? A 2.094 cm B. 524 cm C. 262 cm
Answer:
C. 262 cm
Step-by-step explanation:
Use the formula for the volume of a sphere, V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³
Since the diameter is 10 cm, the radius will be 5 cm
Plug in the radius into the formula:
V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex](5³)
V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex](125)
V = 523.6
Since the bowl is a hemisphere, divide this by 2:
523.6/2
= 261.8
Rounding to the nearest cm, the volume of the bowl is 262 cubic cm.
So, the correct answer is C. 262 cm

Two trains leave stations 196 miles apart at the same time and travel toward each other. One train travels at 80 miles per hour while the other travels at 60
miles per hour. How long will it take for the two trains to meet?
Answer:
The time at which the two trains will meet is 1 hour and 24 minutes
Step-by-step explanation:
The distances between the two trains = 196 miles
The direction of the two trains = Towards each other
The speed of one of the trains = 80 miles per hour
The speed of the other train = 60 miles per hour
Let 't' represent the time at which the two trains meet, we have;
80·t + 60·t = 196
∴ 140·t = 196
t = 196/140 = 7/5
The time at which the two trains will meet, t = 7/5 hours = 1.4 hours = 1 hour, 24 minutes.
