2x + 7 = 19
X=?
Which one is the answer
Answer:
x=6
Step-by-step explanation:
first you subtract 7 and 7 and you also have to subtract 7 and 19 and the answer will be 12 then you divide 2 and 2 to make it only x so if you divide 2 and 2 you also have to divide the 12 so 12 divided by 2 equal 6 so the x is equal to 6
any answers? im bit stuck on this
Step-by-step explanation:
The vertical angles are congruent. The right angles are congruent. There are 2 angles of a triangle congruent to 2 angles of anther triangle. By AA Similarity the triangles are similar.
Statement A. (vertical angles are congruent)
Statement D. (right angles are congruent)
Triangle AEC is similar to triangle BDC.
Statement E is true but does not help.
Correct statement of proportional side lengths:
BD/AE = CD/CE
x/150 = 200/50
x/150 = 4
x = 600
P.S. I think there is a mistake in the problem. I don't think that statement E is correct. It is a true statement, but it is useless. Statement F is false.

Find the value of x.
Answer:
-5
Step-by-step explanation:
Distribute 4(x+6) = 4x+6
Since the angle are congruent to eachother set them equal to oneanother
4x+6 = 5x+11
Subtract 4x on both sides.
6 = x+11
Subtract 11 on both sides.

Brian goes to schol 6 hours per day, works 4 hours perday, and sleeps for 9 hours per day. What is the ratio of hours Brian works to hours Brian sleeps?
The ratio of hours Brian works to hours Brian sleeps is 4/9.
What is ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
Brian goes to school 6 hours per day, works 4 hours per day, and sleeps for 9 hours per day.
So, the ratio of hours Brian works to hours Brian sleeps
= 4/ 9
Hence, the ratio is 4/9.

To amend a country's constitution 7/9 of the 69 states in that country must approve the amendment. If 52 states approve an amendment will the constitution be amended
Answer:
Constitution will not be amended.
Step-by-step explanation:
To amend the country's constitution, number of states should approve the amendment = [tex]\frac{7}{9}[/tex] of 69
= [tex]\frac{7}{9}\times 69[/tex]
= 53.67
≈ 53 states
But the states who approved the amendment = 52
And 52 < 53
Therefore, constitution will not be amended.

Linda needs to have her car towed. Little Town Auto charges a flat fee of $75 plus $2 per miletowed. Write a function expressing Linda's towing cost, C, in terms of miles towed, x. Find thecost of having a car towed 14 miles.
The cost of having a car towed 14 miles is $103.
To express Linda's towing cost, C, in terms of miles towed, x, we can use the given information that Little Town Auto charges a flat fee of $75 plus $2 per mile towed.
The function for the towing cost, C, can be written as:
C(x) = 75 + 2x
Where x represents the number of miles towed.
To find the cost of having a car towed 14 miles, we substitute x = 14 into the function:
C(14) = 75 + 2(14)
C(14) = 75 + 28
C(14) = 103
Therefore, the cost of having a car towed 14 miles is $103.
