Answer:
a = -4
Step-by-step explanation:
a + c = 6
substitute 10 for 'c'
a + 10 = 6
a = -4
Answer:
a has to be a negative since c is equal to 10 so a is -4 because -4 + 10= 6

what makes 3+7+2= ? +2 true? HELP
Answer:
3 + 7 + 2= 12
Step-by-step explanation:
It is made true because the equation adds up to the number. If we take 3+7 it equals to 10. Then we take 10 and add it to 2, which gives us 12.

The value of the missing number x will be 10.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Let the missing number be x. Then the equation can be written as,
3 + 7 + 2 = x + 2
Simplify the equation, then the value of the variable x will be
3 + 7 + 2 = x + 2
3 + 7 + 2 - 2 = x
x = 3 + 7
x = 10
The value of the missing number x will be 10.

ø = pie/6 radians. identify the terminal point and tan ø
Answer:
Terminal point: (√3/2, 1/2); tan θ = √3/3
Step-by-step explanation:
The terminal point is (√3/2, 1/2) and the value of tanθ is √3/3 option (A) is correct.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
θ = π/6
Taking tan on both sides:
tanθ = tanπ/6 = 1/√3 = √3/3
Terminal points:
= (cosπ/6, sinπ/6)
= (√3/2, 1/2)
Thus, the terminal point is (√3/2, 1/2) and the value of tanθ is √3/3 option (A) is correct.

part b
2
The y - intercept is the graph corresponds to the rate at which Mia spends the quarters.
And, The value of slope will be 2.
What is Equation of line?The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
She spends them at a rate of two every minute until she runs out.
Now,
Since, She spends them at a rate of two every minute until she runs out.
And, The number of quarters Mia has is graphed over time.
We know that;
Usually we represent the independent variable (time) by x and dependent variable (quarters) by y.
Hence, The y - intercept is the graph corresponds to the rate at which Mia spends the quarters.
So, The slope = 2/1
= 2
Thus, The y - intercept is the graph corresponds to the rate at which Mia spends the quarters. And, The value of slope will be 2.

Elizabeth has $680 to spend at a bicycle store for some new gear and biking outfits.
Assume all prices listed include tax.
• She buys a new bicycle for $437.63.
• She buys 2 bicycle reflectors for $17.63 each and a pair of bike gloves for $18.11.
She plans to spend some or all of the money she has left to buy new biking outfits
for $35.19 each.
What is the greatest number of outfits Elizabeth can buy with the money that's left
over?
Answer: 5 outfits
Step-by-step explanation: 17.63x2=35.26
437.63+35.26+18.11=491
680-491=189
189 divided by 35.19= 5 (rounded)

A performing arts group has 23 members and adds 2 members per
month. Write an equation in slope-intercept form to represent the number
of members y in x months.
y=2x+23
2x is the for the number of people added every month and 23 is for the number you start with
The equation in slope-intercept form to represent the number of members y in x months is : y = 2x + 23
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
In slope-intercept form, an equation of a line is represented as y = mx + b, where m is the slope (or rate of change) and b is the y-intercept (or the point at which the line crosses the y-axis).
Let's represent x is the number of months and y is the number of members.
The number of members y in x months is a linear function of the number of months, with a slope of 2 (the number of members added per month) and a y-intercept of 23 (the number of members at the beginning).
Thus, the equation in slope-intercept form to represent the number of members y in x months is : y = 2x + 23

Given:
Drawing a vowel from letter tiles that spell out MATHEMATICS.
Chances = [tex]\dfrac{?}{?}[/tex]
To find:
The correct values for the blanks.
Solution:
Vowels are a, e, i, o, u.
In MATHEMATICS, the vowels are A, E, A, I.
Number of vowels = 4
We know that,
[tex]Probability=\dfrac{\text{Number of selected vowels}}{\text{Total number of vowels}}[/tex]
[tex]Probability=\dfrac{1}{4}[/tex]
So, the chance of drawing a vowel from letter tiles that spell out MATHEMATICS is [tex]\dfrac{1}{4}[/tex].
Blank 1: 1
Blank 2: 4
Therefore, the value for blank 1 is 1 and the value for blank 2 is 4.

to under stand this think of a rectangle, or square. that's the yard, then
we know the total area of that rectangle or square, some how. :/ they just tell us, then they tell us the length , or one side of our rectangle or square.
we just have to find the other side.
area of yard (rectangle) = Length * Width
area = L * W
81 = 12 * W
use your algebra skills... ( my calculus prof. tells us that we are all bad at it :))
81/12 = W
6.75 = W
the width of the yard is 6.75 meters

When I have walked 20% of the way to school, I have 1200 metres more to walk than when I have 20% of the walk remaining.
How far, in metres, is it from my home to my school?
Given:
I have walked 20% of the way to school.
I have 1200 metres more to walk than when I have 20% of the walk remaining.
To find:
The distance from home to school.
Solution:
Let x be the distance from home to school.
I have already walked 20% of the way to school and i have 1200 metres more to walk than when I have 20% of the walk remaining.
It means 1200 is [tex]100\%-20\%-20\%=60\%[/tex] of the total distance from home to school.
[tex]1200=\dfrac{60}{100}x[/tex]
[tex]1200=0.6x[/tex]
[tex]\dfrac{1200}{0.6}=x[/tex]
[tex]2000=x[/tex]
Therefore, the distance from home to school is 2000 metres.
How far, in metres, is it from my home to my school is 2,000 metres.
First step is to formulate
1200/(1-2×20%)
Second step is to find how far in metres
Distance=1200/(1-0.4)
Distance=1200/0.6
Distance=2,000
Inconclusion how far, in metres, is it from my home to my school is 2,000 metres.
