Answer:
isosceles triangle . your welcome
The short answer is to solve one equation for one variable, then swap that variable in a different equation.
Example:
2x + 2y = 6
y-x = 1
Step 1: solve either equation for a variable: (#2) y = x+1
Step 2: substitute for your solved variable (I can substitute x+1 for y)
(#1) 2x + 2(x+1) = 6
2x + 2x + 2 = 6
4x + 2 = 6
4x = 4
x = 1
now use x=1 to solve for y in either original equation

Step-by-step explanation:
Answer:
c? I don't really see the expression
1. first you have to find what they ran so what I did was take 28.5 km and divided by 3 because the ratio is 5:2 and 3 is the number difference. 28.5 km divided by 3 = 9.5 so every ratio is going into a 9.5 km part. For example, if the ratio was 2:1 the km ratio would be 19 km: 9.5 km. so I to 9.5 x 5=47.5 km and 9.5*2=19 km
so the 5:2 ratio is equal to 47.5 km : 19 km
The combined running distance would be 66.5 km
2. If the recommended ratio 5:2:3 and Kate wants to have 22 grams of protein(middle) that means her carbohydrates and fat would have to go up 2 x11 =22 so you would do the 5:2:3 ratio and times all three by 11. so the new ratio is 55:22:33. the 55 are your carbohydrates, the 22 are your proteins, and the 33 are your fats. The new ratio is 55:22:33
If Kate plans to eat 22g of protein she woulg have to have 55g of carbohydrates with it. Also she will have to have 33g of fats.
Hope this helps!
Tell me if these are correct.
