5y=25

Both side divided 5,

y=5

Equation-1, y=5

x+2(5)=8

x+10=8

Both side -10

x+10-10=8-10

x=-2

Equation-2, y=5

-x+3(5)=17

-x+15=17

Both side -15

-x+15-15=17-15

-x=2

Answer:

Exact form

5/8

Decimal form

0.625

Step-by-step explanation:

Answer:

-5/8 or -0.625

Step-by-step explanation:

divide both sides by 8

[tex]\frac{8(x+6)}{8} =\frac{43}{8}[/tex]

Simplify

[tex]x+6 = \frac{43}{8}[/tex]

Subtract 6 from both sides

[tex]x+6 - 6 = \frac{43}{8} -6[/tex]

Convert the fraction to decimal and simplify

[tex]5.375 - 6 = -0.625[/tex]

Simplified:

[tex]-\frac{5}{8}[/tex]

This expression is a binomial; it has two terms.

Answer:

x less 21.5

Step-by-step explanation:

Given : the algebraic expression x - 21.5

a. 21.5 decreased by x

the expression becomes 21.5 - x

b. x more than 21.5

more than means we add , so expression becomes 21.5 +x

c. 21.5 minus x

For minus we use subtraction symbol,

so the expression becomes 21.5 -x

d. x less 21.5

x less 21.5 , we subtract 21.5

so the expression becomes x - 21.5 . that is the given expression

Answer:

the 3rd choice is correct

Step-by-step explanation:

Answer:

Arc length is equal to [tex]\theta r[/tex] where [tex]\theta[/tex] is the angle in radians and [tex]r[/tex] is the radius.

Question 1:

[tex]\frac{\pi}{2}=\frac{\pi}{6}\times3[/tex]

So the angle is CFD.

Question 2:

[tex]\pi=\frac{\pi}{3}\times3[/tex]

So the angle is AFE.

Question 3:

[tex]2\pi=\frac{2\pi}{3}\times3[/tex]

So the angle is AFB.

Question 4:

[tex]\frac{3\pi}{4}=\frac{\pi}{4}\times3[/tex]

So the angle is BFC.

Answer:

the number of cups of strawberries needed in the recipe is ⁵/₄

Step-by-step explanation:

Given;

cups of strawberries needed for the smoothies =  1 and 1/4 cups

To obtain the number of cups of strawberries needed in the recipe as a single fraction, the given mixed fractions will be converted into an improper fraction.

Note: Improper fractions are always greater than 1

Number of cups of strawberries [tex]=1 + \frac{1}{4} = \frac{4 + 1}{4} = \frac{5}{4}[/tex]

Therefore, the number of cups of strawberries needed in the recipe is ⁵/₄

Answer:

The remaining side and angles are [tex]a = 20\sqrt{3}[/tex], [tex]\angle A = 60^{\circ}[/tex] and [tex]\angle B = 30^{\circ}[/tex].

Step-by-step explanation:

According to the information given on statement, we are in front of a right triangle because [tex]\angle C[/tex], opossite to side [tex]c[/tex], is a right angle. Hence, [tex]c[/tex] is the hypotenuse of the right triangle and [tex]b[/tex], a leg. The missing length can be calculated by the Pythagorean Theorem:

[tex]a = \sqrt{c^{2}-b^{2}}[/tex] (1)

If we know that [tex]c = 40[/tex] and [tex]b = 20[/tex], then the length of the missing leg is:

[tex]a = \sqrt{c^{2}-b^{2}}[/tex]

[tex]a = 20\sqrt{3}[/tex]

Lastly, we find the value of the missing angles by means of direct and inverse trigonometric relations:

Angle A

[tex]\angle A = \tan^{-1}\left(\frac{a}{b} \right)[/tex] (2)

Angle B

[tex]\angle B = \tan^{-1} \left(\frac{b}{a} \right)[/tex] (3)

If we know that [tex]a = 20\sqrt{3}[/tex] and [tex]b = 20[/tex], then the values of the missing angles are, respectively:

Angle A

[tex]\angle A = \tan^{-1}\left(\frac{a}{b} \right)[/tex]

[tex]\angle A = 60^{\circ}[/tex]

Angle B

[tex]\angle B = \tan^{-1} \left(\frac{b}{a} \right)[/tex]

[tex]\angle B = 30^{\circ}[/tex]

The remaining side and angles are [tex]a = 20\sqrt{3}[/tex], [tex]\angle A = 60^{\circ}[/tex] and [tex]\angle B = 30^{\circ}[/tex].

Answer: 24 years

Step-by-step explanation:

Let Laurel's age be represented by x.

Since Maye is 28 years and he is 12 years older than 2/3 of Laurel's age, this can be represented in an equation as:

(2/3 × x) + 12 = 28.

2x/3 = 28 - 12

2x/3 = 16

Cross multiply

2x = 16 × 3

2x = 48

Divide by 2

x = 48/2

x = 24

Therefore, Laura is 24 years

Answer:

9/25

Step-by-step explanation:

Our box contains 10 socks. (6, which are black and 4 which are red)

Probability of picking 1 black sock will be 6/10

Number of ways it can occur / Total number of outcomes.

In this question we pick two socks, one black firstly and another black, in the second turn. When we say AND, it means intersection

P (B₁ ∩ B₂) = 6/10 . 6/10

When the events are independent, the probability of the intersection will be the product of the probabilities,

P (B₁ ∩ B₂) = 36/100 = 9/25

Answer:

68%

Step-by-step explanation:

Empirical rule formula

= 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .

95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .

From the above question,

Mean = 16 years

Standard deviation = 1.7 years

Score = 14.3 years

We have to find the number of standard deviation to determine the percentage

Hence,

14.3 = 16 - 1.7x

Collect like terms

1.7x = 16 - 14.3

1.7x = 1.7

x = 1.7/1.7

x = 1

This means the data falls within 1 standard deviation from the mean hence, the probability of the gorilla living longer than 14.3 years is 68%
