The equivalent fraction using the multiplier 2 5/8
Answer:
21/8
Step-by-step explanation:
The equivalent fraction using the multiplier 2 5/8 is (21a) / (8b).
To find the equivalent fraction using the multiplier 2 5/8, we need to multiply the original fraction by 2 5/8.
Let's assume the original fraction is "a/b".
The equivalent fraction will be:
Equivalent Fraction = (2 5/8) * (a/b)
To simplify this, we first need to convert 2 5/8 to an improper fraction.
To do that, multiply the whole number (2) by the denominator (8) and add the numerator (5) to get the new numerator.
The denominator remains the same:
2 5/8 = (2 * 8 + 5) / 8 = 21/8
Now, the equivalent fraction becomes:
Equivalent Fraction = (21/8) * (a/b)
To find the final equivalent fraction, we can simply multiply the numerators together and the denominators together:
Equivalent Fraction = (21 * a) / (8 * b)
So, the equivalent fraction using the multiplier 2 5/8 is (21a) / (8b).

Given that vector u has an initial point of (2,-1 ) and a terminal point of (3, 1) and vector v = (- 6, 7) , find v - u.
Answer:
v-u = (-7,5)
Step-by-step explanation:
Given
u has an initial point of (2,-1 ) and a terminal point of (3, 1)
And
v = (-6,7)
First of all we have to find the vector u. for this purpose the initial point is subtracted from the termination point.
Let
[tex]P_1 = (2,-1)\\P_2 = (3,1)\\then\\u = P_2-P_1\\= (3,1) - (2,-1)\\= (3-2, 1+1)\\=(1,2)[/tex]
The vector u is (1,2)
Now we have to find v-u
So,
[tex]v-u = (-6,7) - (1,2)\\= (-6-1,7-2)\\=(-7,5)[/tex]
Hence,
v-u = (-7,5)

9. Zay's age is twice his sister Taylor's age. If they add their ages together,
they get 27. How old are Zay and Taylor?*
A. Zay is 12; Taylor is 15
B. Zay is 18; Taylor is 9
C. Zay is 16; Taylor is 8
D. Zay is 9; Taylor is 18
Answer:
d
Step-by-step explanation:i use my brain ;)
Answer: B
Step-by-step explanation: it says that their combined age is 27 so that is what the equation must equal. It says that Zay is twice Taylor's age so lets say Taylor's age is X, Zay's age would be 2X. Combined it would be 3x. So the equation is
27= 3X
Now if you divide by 3 in both sides you should get 9. Now that's Taylor's age. Multiply by 2 and you get 18 AKA Zay's age.

Consider the equation 2(ax+3)=4x−3(4x+8). For what value of a is there no solution to the equation?
Answer:
the value of [tex]a[/tex] such that there is no solution to the equation is [tex]a = -4[/tex].
Step-by-step explanation:
Let first simplify the expression presented on statement. The equation has no solution if and only if [tex]a[/tex] is eliminated in the process and an absurd is the result (i.e. [tex]0 = 7[/tex]).
[tex]2\cdot (a\cdot x + 3) = 4\cdot x -3\cdot (4\cdot x + 8)[/tex]
[tex]2\cdot a\cdot x +6 = 4\cdot x -12\cdot x -24[/tex]
[tex]2\cdot a \cdot x+6=-8\cdot x-24[/tex]
[tex]2\cdot a\cdot x +8\cdot x = -30[/tex]
[tex]2\cdot (a+4)\cdot x = -30[/tex]
[tex](a+4)\cdot x = -15[/tex]
To obtain an absurd, we need that [tex]a+4 = 0[/tex]. Hence, the value of [tex]a[/tex] such that there is no solution to the equation is:
[tex]a = -4[/tex]
Let prove the certainty of the result. We find that an absurd exist: ([tex]a = -4[/tex])
[tex]0 = -15[/tex]
Considering the equation
[tex]\rm 2(ax+3) = 4x - 3(4x+8) \\[/tex]
The equation given above has no solution when a = -4
On simplifying the given equation we can find that
[tex]\rm 2(ax + 3) = 4x-3(4x+8)\\2ax + 6 = 4x- 12x-24 \\2ax +6 +24 = -8x \\2ax +30 = -8x \\2ax+8x +30 = 0[/tex]
The equation has no solution when the equality of both sides does not hold true .
Hence by observation we can say that the equation has no solution when
[tex]\rm 2ax = -8x \\\\2a =-8\\\bold{a =-4} \\[/tex]
So the equation given above has no solution when a = -4.

Allison’s cupcake and cookie budget for her party is $105. She would like to have at least 40 cupcakes and cookies combined, and would like to have at most 5 more cupcakes than cookies. If cupcakes sell for $2.50 and cookies for $1.50, which system of inequalities could help Allison determine possible numbers of cupcakes (a) and cookies (b) that she should buy? ( a ≥ 0 , b ≥ 0 )
Answer:
a + b ≥ 40
a + 5 ≤ b
2.50a + 1.50b ≤ 105
Step-by-step explanation:
We are told she would like to have at least 40 cupcakes and cookies combined.
If a is number of cupcakes and b is number of cookies, then this inequality is;
a + b ≥ 40
Secondly, we are told she would like to have at most 5 more cupcakes than cookies.
Thus, the inequality is;
a + 5 ≤ b
Lastly, we are told that cupcakes sell for $2.50 and cookies for $1.50
Thus, the inequality is;
2.50a + 1.50b ≤ 105
Finally, the 3 inequalities are;
a + b ≥ 40
a + 5 ≤ b
2.50a + 1.50b ≤ 105
