Answer:
x = 5
Step-by-step explanation:
Solve for x:
-1 - 5 (-x - 1) + 4 x = 49
-5 (-x - 1) = 5 x + 5:
(5 x + 5) + 4 x - 1 = 49
Grouping like terms, 5 x + 4 x - 1 + 5 = (5 x + 4 x) + (-1 + 5):
((5 x + 4 x) + (-1 + 5)) = 49
5 x + 4 x = 9 x:
9 x + (-1 + 5) = 49
5 - 1 = 4:
9 x + 4 = 49
Subtract 4 from both sides:
9 x + (4 - 4) = 49 - 4
4 - 4 = 0:
9 x = 49 - 4
49 - 4 = 45:
9 x = 45
Divide both sides of 9 x = 45 by 9:
(9 x)/9 = 45/9
9/9 = 1:
x = 45/9
The gcd of 45 and 9 is 9, so 45/9 = (9×5)/(9×1) = 9/9×5 = 5:
Answer: x = 5

What is m ZABC?
c=67 d=60
mABC = 60°
mABC = 67 °
mABC = 120°
mABC = 127°
Answer:
m∠ABC = 127°Step-by-step explanation:
From triangle BCD:
m∠BCD + m∠CDB + m∠DBC = 180°
67° + 60° + m∠DBC = 180°
m∠DBC = 180° - 127°
An angle ABD is straight angle, so:
m∠ABC + m∠DBC = 180°
m∠ABC + 180° - 127° = 180°
m∠ABC = 127°

2. Can a triangle have sides with the given lengths? Explain.
1 ft, 3 ft, 7 ft
a. No, because 7+1>3 contradicts the triangle inequality theorem.
b. Yes, because 1+3<7 satisfies the triangle inequality theorem.
c. Yes, because 7+1>3 satisfies the triangle inequality theorem.
d. No, because 1+3<7 contradicts the triangle inequality theorem.
Answer:
option D
Step-by-step explanation:
Sum of measure of any 2 sides of a triangle should be greater than the measure of third side.
The triangle will not have the sides 1 foot, 3 feet, and 7 feet, as these sides do not satisfy the triangle inequality theorem so, option D is correct.
What is inequality?An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. It is most frequently used to compare the sizes of two numbers on the number line.
Given:
The sides of the triangle are, 1 foot, 3 feet, and 7 feet,
We know that the sum of two sides of a triangle is always greater than the third side,
Calculate the sum of sides as shown below,
1 + 3 = 4
Thus, 1 + 3 < 7.
Therefore, these are not the sides of the triangle.

Step-by-step explanation:
Find 62÷2. Use the distributive property.
Answer: The distributive property tells us how to solve expressions in the form of a(b + c). The distributive property is sometimes called the distributive law of multiplication and division. ... Then we need to remember to multiply first, before doing the addition!
Step-by-step explanation: According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
Answer: 31
First, we can break down the number 62.
We will break the number 62 down into 60 + 2.
Now, we will divide the numbers we get after we break down 60.
60 ÷ 2 = 30
2 ÷ 2 = 1
30 + 1 = 31
The answer to your question is 31.

Both the race cars will hit the ground at the same time.
The concept used here is free fall formula which can be defined as . Free fall means that an object is falling freely without a forces acting upon it except gravity, a described constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1\/2 gravity x the square of the time falling. Velocity is described as gravity x time.
Here the two cars are free falling in the vertical direction and the initial velocity in the vertical direction is zero. So the landing time of both the cars is only related to the height and the acceleration of gravity.
Hence, the cars are falling from the same height, h and g are the same so they take same time to touch the ground.

6x - 8-10 = 2 (2x+8) + 2x + 2
Answer:
0 = 36 (No Solution)
Step-by-step explanation:
6x - 8 - 10 = 2(2x + 8) + 2x + 2
Add -8 and -10 = -18
6x + -18 = 2(2x + 8) + 2x + 2
Distributing. 2 x 2x & 2 x 8
6x + -18 = 4x + 16 + 2x + 2
Combine light terms.
6x + -18 = 6x + 18
Add 18 to both sides.
6x = 6x + 36
Subtract 6x
0 = 36

The populations of Cities A and B are 3.7 x 105 and 2,115,000, respectively. The population of City C
is twice the population of City B. The population of City C is how many times the population of City A?
Answer:
a = 370,000
b = 2,115,000
c = 4,230,000
city c is 11.4 times the population of city a
Step-by-step explanation:
10 to the 5 degree is 100,000. multiply that by 3.7 to get the population of City a.
City C is 2,115,000 * 2.
divide the population of City C by the population of City a.
4,230,000 ÷ 370,000= 11.43
