Answer:
1) 4
2) y <= 9
3) NO SOLUTION
4) 24
5) 5 cards
Step-by-step explanation:
1st pic) 2x + 7 = 15
2x + 7 = 15
<u> -7 -7</u>
2x = 8
divide by 2 to isolate x
<u>x = 4</u>
2nd pic) y - 3 <= 6
y - 3 <= 6
<u> +3 +3</u>
<u>y <= 9</u>
<u />
3rd pic) x + 0.5 = x + 6
x + 0.5 = x + 6
<u> -0.5 -0.5</u>
x = x + 5.5
NO SOLUTION
4th pic) 5m + 10 <= 130
5m + 10 <= 130
<u> -10 -10</u>
5m <= 120
divide by 5 to isolate the m
<u>m <= 24</u>
5th pic) 2c - 8 > 0
2c - 8 > 0
<u> +8 +8</u>
2c > 8
divide by 2 to isolate the c
<u>c > 4</u>
Answer:To make 5 batches, Jude needs to use 20 packages of pre-mixed mortar.
Jude uses 9 quarts of water to make 3 batches of cement
If jude uses 16 packages of pre-mixed mortar, he will need to use 12 quarts of water
To make 0.5 batch of cement , Jude should use 2 packages of pre-mixed mortar
Step-by-step explanation:
- 14/11 is an irrational number. It cannot be a natural, integer, or rational number because it is not a whole number.
Your answer is: B) Irrational number
Have an amazing day and stay hopeful!
We are given equations y =3.5x and y=25x +40.50.
Where x represent time in hours and y represents cost in dollars.
We need to determine that which equation is not the equation of a proportional relationship?
In first equation we have slope 3.5 and y-intercept 0.
In second equation, we have slope 25 and y-intercept 40.50.
<em>In order to have a a proportional relationship, there should be y-intercept =0.</em>
<h3>Therefore, y= 25x + 40.50 is not the equation of a proportional relationship.</h3>
Answer:
y=5x+8
Step-by-step explanation:
You need have the slope-intercept formula:
y=mx+b
m=slope
b=y-intercept
You replace the m and b with the slope and y-intercept which is 8
y=5x+8
Hope this helps!
