Answer:
C. 78°
Step-by-step explanation:
The sum of angles in a triangle is 180°.
(7x-6)° +(4x+11)° +43° = 180°
11x +48 = 180 . . . . . divide by °, simplify
11x = 132 . . . . . . . subtract 48
x = 12 . . . . . . . divide by 11
Then the measure of angle T is ...
∠T = (7x -6)° = (7(12) -6)°
∠T = 78°
Answer:
Step-by-step explanation:
percentage of graduates with loan = 62%
total sample = 50
Number of student in the sample with student loan
= (percentage of graduates with loan) x (total sample)
= 62% x 50
= 31
Proportion of student in the sample with student loan =
You have to use the order of operations when evaluating algebraic expressions. The m<span>nemonic device is PEMDAS, which stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. So the first thing is to solve what's in the parentheses.</span>
Answer: B) a + c = 10
8a + 5c = 59
Step-by-step explanation:
We know that 10 total people went, so the first equation has to be equal to 10. The total was $59, so the second equation should be set equal to $59. Now that the second equation is for cost, we must make it 8a + 5c to represent the cost of the adult and child tickets which are $8 and $5, respectively.
Answer:
B
Step-by-step explanation:
Notice that if we divide our given equation (2x - 4 = 6) by 2 from both sides, we get:
(2/2)x - (4/2) = (6/2)
x - 2 = 3
Now, notice what happens if we multiply this by -3:
-3 * (x - 2) = 3 * (-3)
-3 * x + (-3) * (-2) = -9
-3x + 6 = -9
This matches B.
Hope this helps!
