Answer: The pics wont lode

Step-by-step explanation:

The total money would Gavin have after 10 weeks of savings is $ 170 and the required expression is 100 + 7w  

A mathematical expression is a combination of numbers, symbols, and operators that represents a mathematical relationship or calculation. It is written in a way that follows specific rules of mathematical notation, such as using parentheses to indicate the order of operations.

Here we have

Gavin is saving up to buy a new phone.

He already has $100 and can save an additional $7 per week using money from his after-school job

Let us assume that he worked for 'w' weeks  

The amount earned for 'w' weeks = 100 + 7w

Hence, the required expression is 100 + 7w  

The total amount saved in 10 weeks = 100 + 7(10) = $ 170

Therefore,

The total money would Gavin have after 10 weeks of savings is $ 170 and the required expression is 100 + 7w

Answer:

[tex]90^{\circ}[/tex]

Step-by-step explanation:

The interior angles of all triangles sum up to [tex]180^{\circ}[/tex]. Therefore, we can write the following equation:

[tex]4x+5x+9x=180[/tex], where [tex]x[/tex] is some constant.

Combining like terms, we have [tex]18x=180,\: x=10[/tex].

Therefore, the angles of this triangle are [tex]4(10)=40^{\circ}, \: 5(10)=50^{\circ}, \: 9(10)=90^{\circ}[/tex], the largest of them being [tex]\fbox{$90^{\circ}$}[/tex].

Step-by-step explanation:

(x + 8) / (5x - 1) > 0

Multiply both sides by (5x - 1)², which is always positive for all real values of x in the domain.

(x ≠ 1/5)

=> (x + 8)(5x - 1) > 0

=> x < -8 or x > 1/5.

The answer is the 2nd option.

Answer: The dolphin's average speed is 3 mph

Step-by-step explanation: The basic equation is Speed = Distance ÷ Time

S = d/t

To find miles per hour, divide the distance in miles by the time in hours.

Speed = 12 miles/4 hours .  12÷4 = 3

Speed = 3 mph

Step 1

(-4x-3)-(7x-3) =22​  Equation

Step 2

(-4x-3)-(7x-3) =22​  Simplify

-11x=22

Step 3

-11x=22  Divide

Answer

x=-2

Now we have to,

→ find the required value of x.

Then the value of x is,

→ (-4x - 3) - (7x - 3) = 22

→ -4x - 3 - 7x + 3 = 22

→ -11x + 0 = 22

→ x = -22/11

→ [ x = -2 ]

Thus, the value of x is -2.

Step-by-step explanation:

If you subtract 8from20 there's 11 memeber student councilors left which then you subtract another 8from the remaining 11 students and there would be 3 student councilors left which means

there can only be 2.5 different committees because you can't subtract 3 from 8

Answer:

125790 different committees can be chosen.

Step-by-step explanation:

The principal would like to assemble a committee of 8 students from the 20-member student council.

We need to find How many different committees can be chosen?

Since the order is not important, so we use Combinations to solve the question.

The formula used is: [tex]^nC_r=\frac{n!}{(n-r)!r!} \\[/tex]

In the question given: we have n = 20 and r = 8

Putting values and finding the number of ways committees can be chosen:

[tex]^nC_r=\frac{n!}{(n-r)!r!} \\\\^{20}C_8=\frac{20!}{(20-8)!8!} \\^{20}C_8=\frac{20*19*18*17*16*15*14*13*12!}{12!8!} \\^{20}C_8=\frac{20*19*18*17*16*15*14*13}{8!} \\^{20}C_8=\frac{20*19*18*17*16*15*14*13}{8*7*6*5*4*3*2*1} \\^{20}C_8=\frac{5079110400}{40320}\\^{20}C_8=125970[/tex]

So, 125790 different committees can be chosen.

Whats the Question

Step-by-step explanation:

This doesn't make sense

Answer:

the number of seconds to reach the height is 3 seconds

Step-by-step explanation:

The computation of the seconds that reach the height is as follows;

Given that

h = -16t^2 + 96t + 48

here

H = 192 feet

So,

192 = -16t^2 + 96t + 48

-16t^2 + 96t - 144 = 0

Divide by -16

t^2 - 6t + 9 = 0

t^2 - 3t - 3t + 9

t(t - 3) - 3(t - 3)

t = 3 seconds

Hence, the number of seconds to reach the height is 3 seconds

Answer:

6364 cases

6364 bottles are left

Step-by-step explanation:

From the question, we are given the following

Total bottles of water = 8500bottles

Total cases filled = 2136cases

Required

Number of cases Jane can film with the remaining bottle.

Number of cases Jane can fill = 8500-2136

Number of cases Jane can fill with the remaining bottle= 6364 cases

Number of bottles left = number of cases Jane have left to fill.

Hence;

Number of bottles left = 6364 bottles

Answer:

50 is the answer to this question

Answer:

50

Step-by-step explanation:

Well, you're having trouble with how it's supposed to be 50 right? So I suggest breaking it down a little bit.

As you see:

1100 ÷ 22

1100 and 22 are both divisible by 2 so if we divide both numbers by 2 you get:

550 ÷ 11

now try solving from there!!

If you still don't get it here:

firstly 11 goes into 5 zero times so put nothing

next does 11 go into 55? Yes! it does so how many times does it go into 55?

well let's see: 11 + 11 + 11 + 11 + 11 = 55

now if we count how many 11s there are there is 5! so then you put:

5_

now lets see the next number is 0 and does 11 go into 0? Nope! so we just put:

50 and that is your answer!!

(3+b)*(4+2b)=3*4+3*2b+b*4+b*2b=

Answer:

y = - 8x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 8, then

y = - 8x + c ← is the partial equation

To find c substitute (- 1, 4 ) into the partial equation

4 = 8 + c ⇒ c = 4 - 8 = - 4

y = - 8x - 4 ← equation of line

ANSWER: -1/4

EXPLANATION:

4x-y=9

y=4x-9

(so slope/gradient of this line is 4 as y= mx+c and the coefficient of x here is 4)

(formula for perpendicular slopes) m1 multiplied by m2 = -1, where m= gradient

So, m1 x 4= -1

    m of perp line= -1/4
