Answer:
x= -3
Step-by-step explanation:
7+[tex]\frac{2x}{3}[/tex] = 5
21+2x=15
2x=-6
x= -3
Answer:
x=-3
Step-by-step explanation:
Use PEMDAS to solve. Balance both sides by subtracting 7 from both sides. Then, multiply both sides by 3. Finally, divide the result by 2 to isolate x and you end up with x=-3

In which 3 statements below will the number 24 correctly fill in the blank? A) 2 feet = ___ inches B) 24,000 grams = ___ kg C) 3 gallons = ___ pints D) ___ pints = 12 cups E) 240 mg = ___ grams
Answer:
A,B and C.
Step-by-step explanation:
(A) 1 feet = 12 inches
So, 2 feet = 2 × 12 inches = 24 inches
(B) 1,000 grams = 1kg
So, 24,000 grams = (24,000÷ 1,000) = 24kg
(C) 1 gallon = 8 pints
So, 3 gallons = 3 × 8 pints = 24 pints
(D) 1 pints = 2 cups
So, 12 cups = (12÷ 2) = 6 pints
(E) 1 gram = 1000 mg
So, 240 mg = (240 ÷ 1,000) = 0.24 gram
Hence, A,B and C correctly fill with 24.
If the point (a, b) is
located in Quadrant I, in which Quadrant is
the point (a, -b) located?
Answer:
Quadrant IV
Step-by-step explanation:
In Quadrant I the numbers are both positive.
In Quadrant II the number on the x-axis is negative while the number on the y-axis is positive.
In Quadrant III both numbers are negative.
In Quadrant IV the number on the x-axis in positive while the number on the y-axis is negative.
Since your plot point was (a, -b), the number in the y-axis is negative meaning it's located in Quadrant IV.

Which equation below can be used to determine the missing angle in the triangle?
Select one:
x+75+60=180
75x+60x=180
75+60=x
x+75+60=90
Answer:You can use this fact to solve for the missing angle of a triangle. ... Remember -- the sum of the degree measures of angles in any triangle equals 180 degrees. Below is a picture of triangle ABC, where angle A = 60 degrees, angle B = 50 degrees and angle C = 70 degrees. ... Let x = the degree measure of each angle.

At the craft store, Janice bought a bag of green and yellow marbles. She received 14 green marbles and 11 yellow marbles. What percentage of the marbles were green?
Answer: 56%
Step-by-step explanation:
Since Janice bought a bag of green and yellow marbles and she received 14 green marbles and 11 yellow marbles, the total number of marbles will be:
= 14 + 11 = 25 marbles
Number of Yellow marbles = 11
Number of Green marbles = 14
Total number of marbles = 25
The percentage of the marbles that were green will be:
= Number of Green marbles / Total marbles × 100
= 14/25 × 100
= 14 × 4
= 56%

What fact will help you to find the measure of angles B and C in the diagram shown?
A) An equilateral triangle has 3 congruent angles.
B)
The height of an isosceles triangle bisects the base.
C) The base angles of an isosceles triangle are congruent.
D)
The midsegment of an isosceles triangle is parallel to the base
Answer:
The Answer is C
Step-by-step explanation:
Look at B and C you can see that they have a line on each angle. Also, know that isosceles have two congruent sides. So when looking at this triangle we can infer that C is our best bet.

in a test, a hybrid car drove 4952 yards on 1 cup of gasoline. What is this rate in miles per gallon ?
Answer:45
Step-by-step explanation: There’s 16 cups in a gallon and the car goes 4952 yards per cup. You have to multiply the equivalency of a gallon by the yards to get your total distance in yards. Then, you would have to divide your total in yards (79,232) by the yards in a mile (1760). Your ratio would be around 45 miles per gallon.
