five more than one-third of a number is -2. Find the number
Answer:
x = -21
Step-by-step explanation:
Words To Algebra:Words : Five more than one-third of a number = -2
Algebraic Equation: 5 + (1/3)x = -2
Isolate x:5 + (1/3)x = -2 [tex]\longmapsto\\[/tex] Subtract 5 from both sides
5 + (1/3)x - 5 = -2 - 5
(1/3)x = -7 [tex]\longmapsto\\[/tex] Multiply All sides by 3
(1/3)x * 3 = -7 * 3
x = -21
Check:5 + (1/3)-21 = -2
5 + -7 = -2
-2 = -2

64t-16t^2>28 how do i solve this?
Answer:
0.5 < t < 3.5
Step-by-step explanation:
[Given] 64t-16t^2>28
[Rewrite] 64t - 16t² > 28
[Subtract 28 from both sides] 64t - 16t² - 28 > 0
[Reorder] - 16t² + 64t - 28 > 0
[Solve Using The Quadratic Formula] 0.5 < t < 3.5

Step-by-step explanation:
Answer:
x = 12.633, -0.633
Step-by-step explanation:
x^2 -12x + 36 = 44
the underlined part is (x - 6) ^2
(x - 6)^2 = 44
(x - 6) = ± [tex]\sqrt{44}[/tex] (both positive and negative)
(x - 6 ) = + 6.6332495807108
x = 12.6332495807108 = 12.633
(x - 6 ) = - 6.6332495807108
x = - 6.6332495807108 + 6
= -0.6332495807108 = -0.633

20% of A = 96
15% of B =75
Answer:
(20÷100)×96=19.2
(15÷100)×75=11.25
Answer:
A = 480
B = 500
Step-by-step explanation:
Find A and B??
.
20% of A = 96
[tex]\sf{20\% \times A = 96}[/tex]
[tex]\sf{ \frac{20}{100} \times A = 96}[/tex]

How many gallons of a 50% antifreeze solution must be mixed with 90 gallons of 25% antifreeze to get a mixture that is 40% antifreeze? Use the six-step method.
Let x be the needed volume of 50% antifreeze solution. x gallons of this solution contains 0.50x gal of antifreeze.
Mixing this amount with 90 gal of 25% solution makes a total volume of (x + 90) gal of solution.
90 gal of 25% solution contains 0.25 (90 gal) = 22.5 gal of antifreeze.
The new mixture would then consist of (0.50x + 22.5) gal.
If its concentration of antifreeze is supposed to be 40%, then
(0.50x + 22.5)/(x + 90) = 0.40
Solve for x :
0.50x + 22.5 = 0.49 (x + 90)
0.50x + 22.5 = 0.49x + 44.1
0.01x = 21.6
x = 2160

Theres a 4 at the bottom but i couldn't get it in
Answer:
See answer below.
Step-by-step explanation:
1. Start at point (0,0), This point is where the x-y-axis meet. Do not put a dot
there because this is your starting point.
2. Move to the left over to point -1 3/4 . This place is between -1 and -2, and
closer to -2 because the point is -1 .75. Remember this point is not on the
graph.
3. Now move up from that point to 4.5 and put a dot at that place. The point is in the Q II , to the left top.
