Let us convert the percentages to decimal format first.. so 5% is just 5/100 or 0.05 and 15% is just 15/100 or 0.15
so hmmm, so, let's say it needs "x" amount and "y" amount of each respectively, so, whatever "x" and "y" are, they must add up to 100, and whatever their concentration is, must add up to what the mixture yields
thus
solve for "x"
what's "y"? well, y = 100 - x
Answer:
a= d and b= b
Step-by-step explanation:
circumference falls hand and hand with diameter and radius
a has a circumference of about 301 inches
b is about 62 inches
c is about 75 inches
d is about 314
Answer:
A. (1, -2)
B. the lines intersect at the solution point: (1, -2).
Step-by-step explanation:
A. The equations can be solve by substitution by using the y-expression provided by one of them to substitute for y in the other.
This gives ...
3x -5 = 6x -8
Adding 8-3x to both sides, we get ...
3 = 3x
Dividing both sides by 3 gives ...
1 = x
Substituting this value into the first equation, we can find y:
y = 3(1) -5 = -2
The solution is (x, y) = (1, -2).

B. The lines intersect at the solution point, the point that satisfies both equations simultaneously. That point is (1, -2).
Solution1: 9(x) + (y) = 17
Solution 2: 9(x) + 9(y) = 19
Your graphic organizer ➡(y) - 9(x) = 17
9(y) + 9(x) = 19
(y) = 9(x) + 17(⬅Solution 1)
9(x) + 9(9)(x)+17 = 19 ; 90(x) = -134(⬅Solution 2)
(x) = -67÷45
= -1.48
y = 18 ÷ 5
=3.6.
x-intercept ➡ -67/45
y-intercept: 18/5
⬆
y = 3.6; 18/5 (if that's what you're looking for)
