To find z, you have to divide -3 and 10, which you would get an odd number. That will be your answer for z :)
Step-by-step explanation:
BDC and ACD are complementary with each other. that means together they cover the full 180 degrees of the half circle that can be drawn on one side of a flat line.
180 = 11x + 25 + 4x + 5 = 15x + 30
150 = 15x
x = 10
BDC = 11x + 25 = 11×10 + 25 = 110 + 25 = 135 degrees
ACD = 4x + 5 = 4×10 + 5 = 40 + 5 = 45 degrees
Answer:
$90.
Step-by-step explanation:
We have been given that Philip is going on a 4000 kilometer road trip with three friends. The car consumes 6 liters of gas per 100 kilometers.
Let us find how many liters the car will consume per kilometer.
Now let us find total consumption of gas for the whole trip.
Now let us find total cost of gas for whole trip by multiplying the number of liters gas consumed in whole trip by cost of one liter of gas.
Philip and his 3 friends has gone for the road trip, so the total number of people gone for road trip will be 4.
Therefore, each person will have to pay $90 to split the cost of gas evenly.
Subtracting Negative Numbers
When Subtracting a positive number from a negative number—start at the negative number, and count backwards the additional amount you’re subtracting.
Example: Let’s say we had the problem -5 – 3. This would be read as “negative five minus three.” This can be thought of on a number line, which means we’re going to start at the negative number (-5) and keep counting back the -3, arriving at -8.
