Answer:
$87.90
Step-by-step explanation:
Let the amount of money Hashim had be $Y. As such, if he gives his mother $28, he would have $Y - $28 left.
If he had $15.20 less than his sister and his sister had $75.10, then we can say that what he had left $Y - $28 is equivalent to the difference between $75.10 and $15.20.
This is
$Y - $28 = $75.10 - $15.20
Y = $28 + $75.10 - $15.20
= $87.90
Answer:
The slope is 4...
Step-by-step explanation:
y = mx + c
y = 4x
compare both..
Yes they are similar. I believe one of them is smaller and upside. The size is different but the shape is the same!
Hope this helped :)
Answer:
Proportion states that the two fractions or ratios are equal
Given the equation: ![\frac{1.5}{4x+1} = \frac{0.4}{x+4}](https://tex.z-dn.net/?f=%5Cfrac%7B1.5%7D%7B4x%2B1%7D%20%3D%20%5Cfrac%7B0.4%7D%7Bx%2B4%7D)
By cross multiply we get;
![1.5(x+4) = 0.4(4x+1)](https://tex.z-dn.net/?f=1.5%28x%2B4%29%20%3D%200.4%284x%2B1%29)
Using distributive property; ![a\cdot (b+c) = a\cdot b+ a\cdot c](https://tex.z-dn.net/?f=a%5Ccdot%20%28b%2Bc%29%20%3D%20a%5Ccdot%20b%2B%20a%5Ccdot%20c)
![1.5x + 6= 1.6x + 0.4](https://tex.z-dn.net/?f=1.5x%20%2B%206%3D%201.6x%20%2B%200.4)
Subtract 0.4 from both sides we get;
![1.5x +5.6= 1.6x](https://tex.z-dn.net/?f=1.5x%20%2B5.6%3D%201.6x)
Subtract 1.5x from both sides we get;
![5.6= 0.1x](https://tex.z-dn.net/?f=5.6%3D%200.1x)
Divide both sides by 0.1 we get;
![x = \frac{5.6}{0.1}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B5.6%7D%7B0.1%7D)
Simplify:
x = 56
Therefore, the value of x that satisfy the equation
is, 56
Answer:
The domain of a relation is the set of all the x-terms of the relation.
If an x-term appears twice in a relation, only list in once in the domain
The x-values for those three ordered pairs are 2, -2, and -2. For the first ordered pair, you move two positive units along the x-axis, and then along the y-axis to -11. For the second ordered pair, you first move two negative units on the x-axis to -2, and then 11 positive units on the y-axis
