Answer:
x = 1 11/15
Step-by-step explanation:
Using ratios of similar triangles
3 5.2
-------- = ----------
4 (5.2 + x)
Using cross products
3 * (5.2 + x) = 5.2 * 4
Distribute
15.6 + 3x = 20.8
Subtract 15.6 from each side
15.6-15.6 + 3x = 20.8 -15.6
3x =5.2
Divide each side by 3
3x/3 = 5.2/3
x = 5.2/3
x=52/30
x = 26/15
x = 1 11/15
Answer:
d. Jordan needs 1 and one-half cups of diced chicken for 3 salads
Step-by-step explanation:
cups of chicken are shown on the y axis, number of salads is shown on the x axes. For 3 salads you need 1.5 cups of chicken.
Answer:
Y=X/3+3
Step-by-step explanation:
M= Y2-Y1/X2-X1
= 5-6/6-9
= -1/-3
= 1/3
sub x=6, y=5, M=1/3 into Y=MX+C
5=6/3+C
5=2+C
5-2= 2+C-2
3=C
To add expressions, you should take note that you can only
combine same terms which means they have the same degree of exponents.
-5x^4 + 6x^3 – 43 + 6x^5 – x^2 + 12x + 12
In this expression, you can only combine the constants
because they are the only similar terms:
-5x^4 + 6x^3 + 6x^5 – x^2 + 12x + 12 – 43
-5x^4 + 6x^3 + 6x^5 – x^2 + 12x – 31
The standard form starts with the term with the highest
exponent so you just have to arrange the terms:
6x^5 - 5x^4 + 6x^3 – x^2 + 12x + 12
Answer:
x = 12
Step-by-step explanation:
Given
2(x - 3) = 9 + 3(x - 9) ← distribute parenthesis on both sides
2x - 6 = 9 + 3x - 27, that is
2x - 6 = 3x - 18 ( subtract 3x from both sides )
- x - 6 = - 18 ( add 6 to both sides )
- x = - 12 ( multiply both sides by - 1 ), thus
x = 12
