Answer:
1.5
Step-by-step explanation:
12 / 8 = 1.5
Answer:
14/1.8 = x/4
Step-by-step explanation:
Using similar triangles,
height of man/length of man's shadow = height of tree/length of tree's shadow
1.8/4 = x/14
x/14 = 1.8/4
If we cross-multiply, we have
1.8 × 14 = x × 4
dividing both sides by 4 and 1.8,we have
14/4 = x/1.8
x/1.8 = 14/4
So, the two expressions we have are
x/14 = 1.8/4 and x/1.8 = 14/4.
So, the answer is 14/1.8 = x/4 since the product 1.8 × 14 = x × 4 cannot be expressed in the given ratio.
Answer: X = y - yi - 7i
Y = (x + 7i)/(1 - i)
Step-by-step explanation: for the case of (X) you only need to pass the 7i to the other side with the subtraction sign (-7i), then we get this equation:
x + 7i = y − yi
X = y - yi - 7i
in the case of the (Y), first we select the common multiple.
y - yi = y(1 - i)
if we replace it in the original expression, we get the following equation:
x + 7i = y(1 - i)
after that you can pass the value (1 - i) to the other side dividing,
Y = (x + 7i)/(1 - i)
Answer:
At least 22 hours in a week.
Step-by-step explanation:
Given: Manuela make $15 per hour.
Her employers deduct $125 from her weekly check.
Manuela receives at least $205 in her weekly paycheck.
Lets assume, Manuela working hour in a week be "x".
We know, Total amount on week paycheck=
Now, forming an inequality to determine weekly pay of Manuela.
⇒
⇒
Adding both side by 125
⇒
⇒
Divinding both side by 15
⇒
∴
Hence, Manuela works at least 22 hours per week.
Set the 2 equations equal to each other since they both equal Y. then solve for X by moving all constants to one side and the X's to the other. you should get x=-3
