Answer: 4x - 6 = 563
Suma 6 a ambos lados para aislar la variante 4x.
4x - 6 = 563
+6. +6
4x = 569
Divide ambos lados por 4
4x/4 = 569/4
X = 142.5
Step-by-step explanation:
1. Write as an algebraic equation:
12 + n ≤ 2n - 8
2. Solve for n.
12 + n - 12 ≤ 2n - 8 - 12
n ≤ 2n - 20
n - 2n ≤ 2n - 20 - 2n
-n ≤ -20
Multiply both sides by -1 (this means you must flip the inequality sign).
n ≥ 20
FINAL ANSWER: n ≥ 20
Hope this helps! Feel free to ask for clarification.
Answer:
60
Step-by-step explanation:
Sum the parts of the ratio, 5 + 9 + 13 = 27 parts
Divide the amount of concrete by 27 to find the value of one part of the ratio.
324 ÷ 27 = 12 ← value of 1 part of the ratio , thus
5 parts = 5 × 12 = 60 ← cement
9 parts = 9 × 12 = 108 ← sand
13 parts = 13 × 12 = 156 ← gravel
Answer:
y-intercept is 3
Step-by-step explanation:
We are given table
x: -8 -4 4 8
y: -3 0 6 9
We can select any two points


Firstly, we will find slope

now, we can plug values


now, we can use point slope form of line

we can plug values

now, we can solve for y

For finding y-intercept , we can plug x=0



So,
y-intercept is 3
