Answer:

You should probably double check the problem. The equation you have is just 100-1.25

Step-by-step explanation:

Since x=35 x = 3 5 is a vertical line, the slope is undefined.

Answer:

C

Step-by-step explanation:

Answer:

Stefan originally spent $120 because we can say 180 dollars(164+16), than they want 150 percent. so 180 x 1.5 =120, but he sold it for 180 dollars so he made an additonal 60 dollars. Hoped that helped.

Answer:

About About 21 km/h

Step-by-step explanation: If they travel 63 km in 3 hours then all it is is just 63 divided by 3 or 63/3.

The average speed for the cycle will be 21 km per hour.

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance traveled by time. The unit of speed in miles per hour.

The average speed is defined as the ratio of the total distance traveled and the total time taken by the object.

Given that A student cycles a distance of 63 km in less than 3 hours. The average speed is calculated as:-

Average speed = Distance / time

Average  speed  = 63 / 3

Average  speed = 21 km / hr

Answer:

2600

Step-by-step explanation:

Answer:

2600 candles

Answer:

2x2 = 4 + 2 = 6.

Step-by-step explanation:

Answer:

210°F

110 minutes

Step-by-step explanation:

Given that :

Temperature of cake t minutes after being removed from oven :

f(x)=70+140e^-0.024t

Temperature T the timee it is removed ;

At this point, the time t = 0

f(t)=70+140e^-0.024t

f(x)=70+140e^-0.024(0)

= 70 + 140(1)

= 210°F

how long will it take for the cake to reach a temperature of 80oF

80 = 70+140e^-0.024t

80 - 70 = 140*e^-0.024t

10/140 = e^-0.024t

0.0714285 = e^-0.024t

In(0.0714285) = - 0.024t

−2.639057 = - 0.024t

t = 2.639057 / 0.024

t = 109.9607

t = 110 minutes

Answer:

2,3

Step-by-step explanation:

Let the first number be x

Hence, its next consecutive integer = x+1

[tex]Reciprocal\ of\ the\ first\ integer\ = \frac{1}{x} \\Reciprocal\ of\ the\ second\ integer\ = \frac{1}{x+1} \\\\As\ we\ are\ given\ that\ their\ sums\ are\ \frac{5}{6} ,\\\frac{1}{x} + \frac{1}{x+1} = \frac{5}{6} \\\\Through\ butterfly\ method\ of\ resolving\ the\ denominators\,\\\frac{(x+1)+x}{x(x+1)} = \frac{5}{6} \\\frac{2x+1}{x^2+x} =\frac{5}{6} \\6(2x+1)=5(x^2+x)\\12x+6=5x^2+5x\\\\Now, lets\ bring\ all\ the\ terms\ in\ the\ LHS\ to\ RHS.\\\\Hence,\\0=5x^2+5x-12x-6\\5x^2-7x-6=0\\[/tex]

By Factorizing the expression on the LHS. we get it equal to :-

[tex]5x^2-7x-6=0\\5x^2-10x+3x-6=0\\5x(x-2) + 3(x-2) = 0\\(5x+3)(x-2)=0[/tex]

Hence, we get two solutions for x, x=2, x= -3/5

As x is an integer, x=2 is the most suitable solution in this case.

Hence,

The numbers are 2,3

Answer:

Step-by-step explanation:

Using the formulas to find the amount of flour needed:

Correct choice is d.

Step-by-step explanation:

[tex]( - 3 {x}^{2} - 9x) \div (x + 3) [/tex]

This is the original equation so you will open the brackets.

[tex] - 3 {x}^{2} - 9x \div x + 3[/tex]

The x will cross the division sign making it times x.

[tex]3 {x}^{2} - 9x \times x = 3[/tex]

So you will proceed to multiply the 9x by x making it;

[tex]3 {x}^{2} - 9 {x}^{2} = 3 [/tex]

So you will subtract 9x² from 3x² which won't be possible so it will be negative.

[tex] - 6 {x}^{2} = 3 [/tex]

Then you will square root both sides making it;

[tex] - \sqrt{6 {x}^{2} } = \sqrt{3} [/tex]

So the ² will cancel the √ leaving

-6x=√3

-6x=1.73(Divide both sides by -6)

x=0.288

That's the final answer.

Answer:

-8a-5=3-6a

-8a+6a=3+5

-2a=8

a=8/-2

therefore,a=-4 answer...

Answer:

a = 4

Step-by-step explanation:

Firstly, make all subtraction signs, addition signs which should look like this

-8a + -5 = 3 + -6a

Add 5 to both, -5 and 3.

-8a = 8 + -6a

Add 8a to both -8a and -6a

2a = 8

Divide both by 2

a = 4

Answer:

x=-9

Step-by-step explanation:

2(x-7)-5x=13

Remove the parenthesis

2x-14-5x=13

Collect like terms

-3x - 14 = 13

Move the constant to the right

-3x=13+14

Calculate

-3x=27

Divide on both sides to get the answer

Answer:

x(5) = number of cents

Step-by-step explanation:

If x = the amount of nickels you have, since 1 nickel is 5 cents, you multiply the number of nickels times 5 to get the number of cents. x(5). Examples: 5 Nickels= 5(5) = 25 cents. 7 Nickels = 7(5) = 35. Just plug in the number of nickles for x and solve. Hope this helped! If it did, please give me brainliest. Thanks!

ok bett this is good I guess lol

Answer:

the line crosses the parabola at (-2,4) and (3,9)

Step-by-step explanation:

y=x^2

y=x+6

set them equal to each other

x^2=x+6, now set it equal to zero

x^2-x-6=0, now find the root

(x+2)(x-3)=0, the x=-2, and x=3; now substitute into any of the equation to find the points where graphs intercept

at x= -2, y=(-2)^2=4, so one point is (-2,4)

at x=3, y=(3)^2=9, so other point is (3,9)

the line crosses the parabola at (-2,4) and (3,9)
