Answer:
4.4...
Step-by-step explanation:
20 ÷ 4 1/2
let's change 4 1/2 into an improper fraction.
20 ÷ 9/2
20 is the same thing as 20/1, so we'll express it that way.
[tex]\frac{20}{1}[/tex] ÷ [tex]\frac{9}{2}[/tex]
in order to divide fractions, you must multiply the first number (20/1) by the inverse of the second number (2/9). I'll put it in normal fraction form for clarity.
20 2
--- × ---
1 9
now we multiply straight across.
40
----
9
now we have 40 ÷ 9, which is 4.444...
so your answer is 4.4...
{also 4.4 with a repeating bar (tiny line over the .4)}

The points (6,0) and (z,-8) fall on a line point with a slope of -8.what is the value of z?
what is the value of x
Answer:
[tex]x = 2[/tex]
Step-by-step explanation:
First simplify the equation.
[tex]\frac{7}{9}x -\frac{4}{9} =\frac{1}{4} +\frac{5}{12}[/tex] [tex]\frac{3}{9}x= \frac{3}{12} +\frac{5}{12}[/tex] [tex]\frac{3}{9}x=\frac{8}{12}[/tex] [tex]\frac{1}{3}x=\frac{2}{3}[/tex]Now multiply both sides by 3.
[tex]x = 2[/tex]
I hope it helps you. Please choose my answer as the BRAINLIEST.
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
[tex]\cfrac{7}{9}\:x-\cfrac{4}{9}\:x=\cfrac{1}{4}+\cfrac{5}{12}[/tex]
First, combine [tex]\frac{7}{9} x[/tex] and [tex]-\frac{4}{9} x[/tex] = [tex]\frac{1}{3} x[/tex]
[tex]\cfrac{1}{3}\: x=\cfrac{1}{4} +\cfrac{5}{12}[/tex]
LCM of 4 and 12 is 12, Convert 1/4 and 5/12 to fraction with denominator 12:
[tex]\cfrac{1}{3}\: x=\cfrac{3}{12} +\cfrac{5}{12}[/tex]
Since 3/12 and 5/12 have the same denominator, let's add numerators:
[tex]\cfrac{1}{3}\:x=\cfrac{3+5}{12}[/tex]
[tex]\cfrac{1}{3}\:x=\cfrac{8}{12}[/tex]
Reduce the fraction 8/12 to lowest term by extracting and canceling out 4,
[tex]\cfrac{1}{3} \:x=\cfrac{2}{3}[/tex]
Multiply both sides by 3, reciprocal of 1/3:
[tex]x=\cfrac{2}{3} \times 3[/tex]
Cancel out 3 and 3:
[tex]x=2[/tex]

Subtract 10x2 – 10x + 2 from - 8x2 + 7x – 7.
Answer:
18x^2 - 17x +9
Step-by-step explanation:
Original equations:
10x^2 - 10x + 2
-8x^2 +7x - 7
Calculations:
10x^2 - (-8x^2) = 18x^2
(-10x) - 7x = -17x
2 - (-7) = 9
Together, they make: 18x^2 - 17x + 9

Answer:
24) 10:50
25) 1,2,5,10,50,25
26) 3 inches
27) We multiply 2 by $3.49 to get the total cost. Or in other words multiply the items by the price to get the total
28) B
29) 1/6
30) 21 degrees was the high temperature
Step-by-step explanation:
- I can't see the clock well, but I'll guess its 10:20. 30 minutes after would be 10:50.
- There are 6 common factors of 50 and 100.
1,2,5,10,50,25
- 12/4 is 3.
- A shopper purchased 2 items, each were $3.49 (That is all the info we need to create an equation to solve/estimate the cost of the purchase) We multiply 2 by $3.49 to get the total cost. Or in other words multiply the items by the price to get the total
- We multiply 1/3 by x amount of batches. So in this case we have 2. It becomes 1/3 times 2 = 1/6
- The low temperature is 8 degrees because each line represents a difference of 2 and 10 - 2 = 8. Now to calculate the high temperature, you add 13 to 8 = 21.

Answer:
D
Step-by-step explanation:
The vertex of the triangle is adjacent to 90° on a straight line, so

Given : VU = 8 cm, let SV = n and SU = m
[tex] \tan(45) = \dfrac{8}{m} [/tex][tex]1 = \dfrac{8}{m} [/tex][tex]m = 8 \: \: cm[/tex]so, SU = 8 cm
[tex] \sin(45) = \dfrac{8}{n} [/tex][tex] \dfrac{1}{ \sqrt{2} } = \dfrac{8}{n} [/tex][tex]n = 8 \sqrt{2} [/tex]SV = [tex]8\sqrt{2}[/tex]
now,
The ratio of sides of Triangle SUV is :

Answer:
a) 115°
Step-by-step explanation:
first find the value of angles B and C by doing 180 - 50 =130 and then 130÷2 because B and C are equal
Since the lines BO and CO are bisectors, it means that the angles are halved fo take half of angle B plus half of angle C and add them together = 65 and then do 180-65=115 so the angle BOC is 115°

a) Si al cuadrado de un número se le suma el doble del mismo número y se resta 5, se
obtiene 75. ¿Qué número es?
Ecuación:
• Soluciones:
Construyendo y resolviendo una ecuación, tenemos que el número puede ser 8 o -10.
El número es desconocido, así que lo llamaremos x. El cuadrado del número es [tex]x^2[/tex].El doble es [tex]2x[/tex], sumando al cuadrado, [tex]x^2 + 2x[/tex].Se resta 5, o sea, [tex]x^2 + 2x - 5[/tex].Obtiene 75, entonces: [tex]x^2 + 2x - 5 = 75[/tex].Para encontrar el número, tenemos que resolver una ecuación cuadrática, luego:
[tex]x^2 + 2x - 5 = 75[/tex]
[tex]x^2 + 2x - 80 = 0[/tex]
Ecuación cuadrática con [tex]a = 1, b = 2, c = -80[/tex]
[tex]\Delta = 2^2 - 4(1)(-80)[/tex]
[tex]x_{1} = \frac{-2 + \sqrt{324}}{2} = 8[/tex]
[tex]x_{2} = \frac{-2 - \sqrt{324}}{2} = -10[/tex]
El número puede ser 8 o -10.

Answer:
q(8) = 39.
Step-by-step explanation:
relate the values
for,
q(x) = 1/2x² + 7
q(8) = 1/2(8²) + 7
q(8) = 39.
Answer:
q(8) = 39
Step-by-step explanation:
To solve this question, you need to plug in (substitute) 8 instead of x:
q(8) = [1/2(8)²] + 7
= (1/2 × 64) + 7
= 32 + 7
= 39
∴ q(8) = 39
