solve for x. 3(x- 4)=15x
Answers
Answer:
x=-1
Step-by-step explanation:
3(x−4)=15x
Use the distributive property to multiply 3 by x−4.
3x−12=15x
Subtract 15x from both sides.
3x−12−15x=0
Combine 3x and −15x to get −12x.
−12x−12=0
Add 12 to both sides. Anything plus zero gives itself.
−12x=12
Divide both sides by −12.
x=
−12
12
Divide 12 by −12 to get −1.
x=−1

A bottle is filled with 635 g of olive oil which has a density of 0.96 g/cm3. What is the volume of the olive oil ?
Answers
Answer:
The volume of the olive oil is 661.4583 cm³
Step-by-step explanation:
The rule of the density of an object is d = M ÷ V, where
M is the mass of the objectV is the volume of the object∵ A bottle is filled with 635 g of olive oil
∴ M = 635 g
∵ The olive oil has a density of 0.96 g/cm³
∴ d = 0.96 g/cm³
→ Substitute them in the rule above
∵ 0.96 = 653 ÷ V
→ Multiply both sides by V
∴ 0.96 V = 635
→ Divide both sides by 0.96
∴ V = 661.4583 cm³
∴ The volume of the olive oil is 661.4583 cm³

Answers
angle 2=42
angle 3=113
The measures of unknown angles are, m∠2 is 42°, m∠1 = 88° and
m∠3 = 113°.
What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
We know vertically opposite angles are of equal measure.
∴ m∠2 is 42°.
We know the sum of all the interior angles in a triangle is 180°.
∴ m∠1 = 180° - 50° - 42°.
m∠1 = 88°.
m∠3 = 180° - 42° - 25°.
m∠3 = 113°.

The graph of the equation y = 1 x + 2 is displayed.
Which equations would intersect the orange line at the
y-intercept? Check all that apply.
Answers
Answer:
A. y = 7x + 2
C. y = 2 - ⁷/3x
D. y - 2 = 4x
Step-by-step explanation:
The equation of any line that would intersect the orange line at the y-intercept, 2, would have the same y-intercept value of 2.
Thus, from the options given, the following equations has y-intercept (b) of 2.
A. y = 7x + 2
C. y = 2 - ⁷/3x
D. y - 2 = 4x
All three equations have a y-intercept value, b, of 2.
Note: option D, y - 2 = 4x, can be rewritten as y = 4x + 2.
Answer: A/C/D

Two computer technicians both charge a fee for a home visit ,plus an hourly rate for their work. Dana charges a $64.95 fee, plus $45/h. Tom charges a $79.95 fee, plus $40/h. For what length of service call do Dana and Tom charge the same amount?
Answers
Answer:
3 hours
Step-by-step explanation:
Step one:
given data
Dana charges
$64.95 fee, plus $45/h.
let the number of hours be x
and the total charges be y
y= 45x+64.95---------1
Tom charges
$79.95 fee, plus $40/h.
let the number of hours be x
and the total charges be y
y= 40x+79.95---------2
Step two:
Equate eqn 1 and 2 to find x
45x+64.95=40x+79.95
collect like terms
45x-40x=79.95-64.95
5x=15
divide by 15
x= 15/5
x= 3 hours

A boat goes 24 miles at a constant speed in 4 hours against a river current.
It takes the boat 3 hours to go the same distance at the same speed with the
current of the river. What is the speed of the boat and what is the current of
the river?
Answers
The speed of the boat is 7 miles/hour and the current of the river is 1 mile/hour.
What is the distance?Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
We have:
A boat goes 24 miles at a constant speed in 4 hours against a river current.
It takes the boat 3 hours to go the same distance at the same speed with the current of the river.
Let's suppose the speed of the boat is x miles/hour and the current of the river is y
x- y = 24/4
x - y = 6 ..(1)
x + y = 24/3
x + y = 8 ..(2)
Adding equation (1) and (2):
2x = 14
x = 7 miles/hour
y = 8 - 7 = 1 miles/hour
Thus, the speed of the boat is 7 miles/hour and the current of the river is 1 mile/hour.
