Answer:

26

Step-by-step explanation:

normally this should be way below your math abilities in 9th grade.

but here as a reminder :

dot operations (like multiplication and division) happen before any dash operations (addition, subtraction).

so when we go through here we see therefore

-32/8 and 5×-2 have to be calculated first (I use × instead of ., because a fit can be so easily missed or misunderstood).

and then : mind the "-" signs to actually sign all terms for the final sum.

so, -32/8 = -4

5×-2 = -10

now we have

40 - 4 - 10 = 26

Answer:

The balance would be $160 from whatever it was before the 4 months.

Step-by-step explanation:

Since the bank balance is being added by 40 for each month for 4 months, 4 * 40 is just 4*4 with an extra zero on the end. so that would be $160.

So if the balance before was $40, then the new balance after 4 months would be $200.

If there's no money previously, then there is now $160 after 4 months.

If there's a value before the $40 for 4 months, let me know and I will explain and tell you what it is.

Answer:

8

Step-by-step explanation:

12 times x (the first square) is equal to 16 times x-2 (the second square)

[tex]12x = 16(x-2)[/tex]

Distributed

[tex]12x = 16x-32[/tex]

Simplified (divided by 16)

[tex]0.75x = x-2[/tex]

Subtract x from both side of the equation

[tex]-0.25x = -2[/tex]

Both negatives cancel each other out

[tex]0.25x = 2[/tex]

0.25 times what equals 2,...

[tex]x = 8[/tex]

Answer:

1

Step-by-step explanation:

(8/8) = 1                                 (4/8) = half                       (0/8) = 0

                                   (5/8) = a bit more than half, so is closer to 1

5/8≈1

Answer:

OPTION A.

Step-by-step explanation:

Put in simple terms

You're asked to Make "h" the subject.

p=0.7(rh + b)

divide through by 0.7

p/0.7 = rh + b

Rearranging

rh + b = p/0.7

rh = p/0.7 – b

divide through by "r"

h = (p/0.7 – b)÷ r.

Option A is your answer.

Notice that they look similar but you gotta see the difference.

The parenthesis covers all that's being divided by r

Step-by-step explanation:

Step-by-step explanation:

here,

x°+15°=5x°-41°[being vertically opposite angle]

15°+41°=5x°-x°

56°=4x°

[tex] \large \sf\frac { 5 } { 4 x - 6} = \frac { 2 } { x - 9} \\ [/tex]

Variable x cannot be equal to any of the values [tex]\sf\frac{3}{2}[/tex],9 as division by zero is not defined. Multiply both sides of the equation by [tex]\sf2\left(x-9\right)\left(2x-3\right)[/tex], the least common multiple of 4x-6 ,x-9.

Use the distributive property to multiply x-9 by 5.

[tex] \large \sf5x-45=8x-12 [/tex]

Subtract 8x from both sides.

[tex] \large \sf5x-45-8x=-12 [/tex]

Combine 5x and -8x to get -3x.

[tex] \large \sf-3x-45=-12 [/tex]

Add 45 to both sides.

Add -12 and 45 to get 33.

 Number of non white players will be the difference of the total players and the white players in the team.

Number of non-white NBA players in the team are 439.6

Key points to focus in the question,

    Number of white players out of total number of players = 16.9% of 529 players

                                                                                            = [tex]\frac{529\times 16.9}{100}[/tex]

                                                                                            = 89.401

                                                                                            ≈ 89.4

     Therefore, number of non-white players in the teams = Total number of players - Number of white players

= 529 - 89.4

= 439.6

     Number of non-white NBA players = 439.6

The line AB is not a perpendicular bisector of CD.

Perpendicular bisectors are lines that divides another line into two equal parts.

From the diagram, we can see that line CD cuts AB at the centre. Hence we can say that CD is a perpendicular bisector of AB.

The same is not applicable to line AB passing through CD. The line AB did not bisect (divide equally) line CD.

Hence we can conclude that line AB is not a perpendicular bisector of CD.
