X+4+5x=6x+4
6x+4=34
6x=30 (minus 4 on both sides)
30÷6=5
hence: x=5
Answer:
14 % pure juice comes from first brand
Step-by-step explanation:
Mixture:
17 gal 30% contains: 17x 30% = 5.10 gal pure juice
Second brand:
8 gal 48% contains: 8x40% = 3.84 gal pure juice
5.10 − 3.84 = 1.26 gal
1.26 gal is coming from 9 gal of first brand
The percentage of first brand is:
(1.26/9) x100 = 14 % pure juice.
An orange ... o grams = ?
a pineapple ... p = 7 * o
p = 870 grams + o
If you would like to know what is the total weight in grams for the pineapple and orange, you can calculate this using the following steps:
7 * o = 870 + o
7 * o - o = 870
6 * o = 870 /6
o = 870 / 6
o = 145 grams
p = 7 * o = 7 * 145 grams = 1015 grams
Result: A pineapple weights 1015 grams and an orange 145 grams.
Answer:
a line that crosses the y-axis in 3, and the x-axis at -0,6
Step-by-step explanation
the number that is NOT x is going to give you the place where the y-intercept (the place where the line crosses the y-axis) is going to be, in this case is 3 so you have to go up 3 times (or units) in the y-axis, then you will use x, AKA the slope (rise over run or rise/run), to find the other points in the plane, in this case the rise=5, so you go up or down by 5 units.
if you went up, then you will take the right for the run, and left if you went down.
the run in this equation the run=1 ( is the same with all non-fraction numbers)
so you need to go 1 unit to the right if you went up and 1 unit to the left if you went down
