Answer: 56.25 of 70% and 93.75pints of 90%
Step-by-step explanation: First find the ratios. One juice is 70% and the other is 95%. Your goal is 85%. This is 15% from 70 and 10% from 95. This means you need (15)/(15+10) of 95, which is 3/5 of all the juice to be 95. This means you will need more of the 95% juice, which makes sense because 85 is closer to 95. So 3:5 and total 150=56.25 of 70% and 93.75pints of 90%

The ordered pair we are looking for is the values of the variables [tex]x[/tex] and [tex]y[/tex], or [tex](x, y).[/tex] We are given that [tex]x=2[/tex], and that the formula to evaluate [tex]y[/tex] is [tex]y = 5^x[/tex]. Note we are given [tex]x[/tex] so we can evaluate [tex]y[/tex] as [tex]y = 5^2 = 25[/tex]. Now, we have both the values of [tex]x[/tex] and [tex]y[/tex], so our ordered pair is thus [tex](x,y) = (2,25).[/tex]
solve for y -2(x + 3y) = 18
Answer:
[tex] \sf\large \: y = \frac{ - 1}{3} x - 3[/tex]
Step-by-step explanation:
Let's solve for y.
−2(x+3y)=18
Step 1: Add 2x to both sides.
−2x−6y+2x=18+2x
−6y=2x+18
Step 2: Divide both sides by -6.
−6y/−6 = 2x+18/−6
y= −1/3x−3

find the point of intersection y=4x-1 y=-2x+5
The point of intersection of the given two lines y = 4x - 1 and y = -2x + 5 is (1, 3).
According to the given question.
We have two equations
y = 4x - 1 ..(i)
and
y = -2x + 5 ..(ii)
As we know that, the point at which two lines intersect is called point of intersection.
Therefore, the point of intersection for the two lines y = 4x - 1 and y = -2x + 5 is given by
Subtracting equation ii from i
y - y = 4x - 1 + 2x -5
⇒ 0 = 6x - 6
⇒ 6x = 6
⇒ x = 1
Substitute the value of x in (i).
y = 4 - 1 = 3
Hence, the point of intersection of the given two lines y = 4x - 1 and y = -2x + 5 is (1, 3).

Given 4x=12x+22 prove x=-4
the required simplified value of given expression 4x = 12x + 32 is x = -4 (hence proved).
Given that,
An expression is given 4x = 12x + 32,
We have to prove x = -4 as of simplified solution.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
4x = 12x + 32
Taking 12x to the left side of the equal sign and it becomes -12x
4x - 12x = 32
Applying subtraction property between 4x and 12
- 8x = 32
Dividing both sides by -6
x = -4

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 310, 304,298,... 310,304,298,... \text{Find the 47th term.} Find the 47th term.
The 47th term in the given arithmetic sequence is 34.
Given,
The arithmetic sequence = 310, 304, 298,......
First term of the sequence, t₁ = 310
Common difference of the sequence, d = t₂ - t₁ = 304 - 310 = -6
nth term of an arithmetic sequence, tₙ = t₁ + ( n - 1) d
We have to find the 47th term of the arithmetic sequence.
That is, n = 47
So,
t₄₇ = 310 + (47 - 1) -6
t₄₇ = 310 + (46 x (-6) )
t₄₇ = 310 - 276
t₄₇ = 34
Therefore, the 47th term in the given arithmetic sequence is 34.

Where A is the amount, P is the initial amount, r is the rate of interest, and t is the number of years.
If $500 had been invested at an annualized rate of 8%, the money would have after 2.5 years. For the quarterly, the value of n will be 4. Then the amount will be
[tex]\rm A = 500 \left (1 + \dfrac{0.08}{4} \right)^{4 \times 2.5}[/tex]
Simplify the equation, then the amount is given as,
A = 500 (1 + 0.02)¹⁰
