Answer:
x= 3 1/2
Step-by-step explanation:
Answer:
You just multiply by 5. the 1st one will be 15.
1:15
2:35
3:100
4:2.5
5a:1 to 6 or 1:6
5b: I have no idea what this one is sorry.
The copy is the exact same as the original, so the scale factor would be 1.
The answer is the first choice
Answer: lemon cremes contain 70 calories. fudge cookies contains 95 calories
Step-by-step explanation:
Let x represent the amount of calories in lemon cremes.
Let y represent the amount of calories in fudge cookies.
Three lemon cremes plus two fudge cookies have 400 calories. This means that
3x + 2y = 400 - - - - - -- - - - -1
Two lemon cremes plus three fudge cookies have 425 calories. This means that
2x + 3y = 425- - - - -- - - - - - 2
Multiplying equation 1 by 2 and equation 2 by 3, it becomes
6x + 4y = 800
6x +9y = 1275
Subtracting,
-5y = - 475
y = - 475/- 5
y = 95
Substituting y = 95 into equation 1, it becomes
3x + 2×95 = 400
3x = 400 - 190 = 210
x = 210/3 = 70
x = 70
Answer:
As follows, (shortened)
Step-by-step explanation:
1.AB=CD (Given)
2.AB+BC=CD+BC ( By additive property, adding BC to both sides)
3.AB+BC=CD+DE (Given, BC=DE, By substitution property replacing BC by DE)
4.AC=CE(By segment addition, and substitution property)
