Let 
x--------> volume of <span>35​% fertilizer
y--------> </span>volume of 25​% fertilizer

we know that
x+y=220-----> x=220-y-----> equation 1
x*0.35+y*.25=220*.29-----> equation 2

substitute equation 1 in equation 2
[220-y]*0.35+0.25*y=63.8----> 77-0.35*y+0.25*y=63.8
0.10*y=13.2------> y=13.2/0.10----> y=132 gal
x=220-y----> x=220-132----> x=88 gal

the answer is
88 gal of 35​% fertilizer
132 gal 25​% fertilizer

Four less than 5 times a number is the same as 26 more than twice the number.
Tju [1.3M]

Answer:

False

Step-by-step explanation:

5x - 4 versus 2x + 26

Imagine x equals 1, then the equations would be:

5(1) - 4 and 2(1) + 26

1 and 28 are not equivalent.

Another example would be x = 6

5(6) - 4 and 2(6) + 26

26 and 38 are not equivalent.

No matter what you replace x with, the expressions are never equal.

point A lies at the intersection of y = x and y = -2/3x + 5. What are the coordinates of A? Express your answer as an ordered pa
torisob [31]
Y = x
y = -2/3x + 5

x = -2/3x + 5
x + 2/3x = 5
3/3x + 2/3x = 5
5/3x = 5
x = 5 * 3/5
x = 15/5 reduces to 3

y = x
y = 3

so ur answer is (3,3)

There are 7 cherries and 3 grapes in a bag. What is the pobability of selecting 2 grapes at random without replacement?
dlinn [17]

Answer:

1/15

Step-by-step explanation:

7+3 = 10 items in the bag

P(grape) = grapes/total

                3/10

No replacement

7 cherries 2 grapes = 9 items

P(grape) =  grapes/total

                    2/9

P(grape, no replacement, grape) = 3/10*2/9

                                                       =1/15
