Angle B measures 67 degrees
Step-by-step explanation:
2x - 13 + 4x - 5 = 90
6x - 18 = 90
+18 +18
6x = 108
6x/6 = 108/6
x = 18
4x - 5
4(18) - 5
= 67

Please help me asap!!
Please answer asap with explanation
Answer:
x^2 = 44y
It's really hard to explain
but if the directrix is y then your problem will have X^2= if it was x then the problem would have y^2=
then you have to have the y on the other side of the equation
and you want to multiply the 11 by 4. always multiply by 4.
this is a good video to understand it go to You.Tube and type

Step-by-step explanation:
find the value of x. 49° x°
Answer:
x = 41
Step-by-step explanation:
All triangle angles add up to 180 so:
x + 90 + 49 = 180
x + 139 = 180
x = 180 - 139
x = 41
what does 45=-3x tell me
Answer: x = -15
Hope this helps :)
Answer:
x = -15
Step-by-step explanation:
[One step multiplication problem]
When solving a one-step multiplication problem the easiest thing to do would be to divide the 'answer' (in this case, 45) by the coefficient (in this case, -3). A negative number times a negative number is a positive number, so x would be a negative number. 45 divided by -3 is -15.
So, x = 15.

Each solar array wing on the International Space Station measures 39 feet by 112 feet. The scale drawing of a solar array wing shown below was made using a scale of 1 inch: 8 feet.
Write the ratio of the area of the wing in the drawing (square inches) to the area of an actual solar array wing (square feet) as a unit fraction.
The drawing is just a large rectangle with the length being 4.875 and there is noting for the width.
Answer:
39-112= -73 or 73
so 73+1/8= 81

Suppose that the probability that your
mail is delivered before 2 pm is .90.
What is the probability that your
mail
will be delivered before 2 pm for two
consecutive days? Give your answer as
a decimal.
Answer:
The probability is 0.81
Step-by-step explanation:
The probability we want to find here is that;
the mail was delivered before 2 pm the first day and also delivered before 2 pm the next day
what we have to do here is to
multiply together, the probability in the two cases (for both days)
So we have this as:
0.9 * 0.9 = 0.81
Answer:
.81
Step-by-step explanation:
Simplify the following fractions to their lowest possible form using the Greatest Common Factor
Answer:
13) 3/6 = 1/2
14) 4/8 = 1/2
15) 6/30 = 1/5
Step-by-step explanation:
GCF OF 3/6 = 3, SO 3/6 = 1/2
GCF OF 4/8 = 4, SO 4/8 = 1/2
GCF OF 6, 30 = 6, SO 6/30 = 1/5

Can somebody help me with this pleaseee!!! Help will be very appreciated And may you explain why it’s a lie .
Answer:
my mother say it is B. she is good at math
Answer: A
Step-by-step explanation:
Answer A is a lie. The most obvious reason being the other two statements can be proven because the y intercept of the exponential IS (0, 1). Secondly, the point (-2, 4) CAN be found on the graph. Option A is the lie because if you look, for x = 10, y = 0. Therefore, the statement that for very large values of x the exponential has very large values of y, is a lie.

Two angles are complementary. The first angle is 2x degrees. The second angle is (3x +5) degrees. Determine the measure of each angle.
Draw the angles, write and equation and solve the measures of each angle.
HELP PLEASE
Answer:
70 and 110
Step-by-step explanation:
First angle -- 2x
Second angle -- 3x + 5
Therefore,
2x + 3x + 5 = 180
5x = 175
x = 35
Therefore, 2x -- 70
3x + 5 -------------110
