Improper fraction = 53/8
decimal = 6.625
percent = 662.5%
Y = 6x - 11
-2x - 3y = -7
Let's use substitution:
-2x - 3y = -7
-2x - 3(6x - 11) = -7
-2x - 18x + 33 = -7
-20x + 33 = -7
-20x = -40
x = 2
----
y = 6x - 11
y = 6(2) - 11
y = 12 - 11
y = 1
----
y = 6x - 11 => 1 ? 6(2) - 11 => 1 = 12 - 11 <--True
-2x - 3y = -7 => -2(2) - 3(1) ? -7 => -4 - 3 = -7 <--True
Answer:
x = 2
y = 1
Hope this helps!
12 * 20% = 12 * 0.20 = 2.4 hours
It will not last his entire shift.
Answer:
4
Step-by-step explanation:
1. AB:BC is 1:2
2. Add the 1 and the 2
(3)
3. Find the distance between -7 and 26
26-(-7) = 33
4. Divide the distance by 3
33/3 = 11
5. Find the distance from A---->B
-7 + 11 = 4
In ΔABC, D and E are the midpoints of AB and AC respectively. We know that the ratio of areas of two similar triangles is equal to the ratio of square of their corresponding sides. Hence, the ratio of the areas ΔADE and ΔABC is ar(ΔADE) : ar(ΔABC) = 1 : 4.
