1x + 7 = 9x + 2 what is x
Answer:
5/8 or 0.625
Step-by-step explanation:
first you'll subtract 1x from the left and subtract 2 from the right
1x+7=9x+2
-1x . -1x
7=8x+2
-2 -2
5=8x
divide this by 8
5/8 or 0.625

harry purchased a 600$ savings bond if he has 1200 in total in the bank at the end of 10 years what was the simple interest rate
Answer:
R = 10%/year
Equation:
r = (1/t)(A/P - 1)
Solving our equation:
r = (1/10)((1200/600) - 1) = 0.1
r = 0.1
Converting r decimal to R a percentage
R = 0.1 * 100 = 10%/year
The interest rate required to get a total amount, principal plus interest, of $1,200.00 from simple interest on a principal of $600.00 over 10 years is 10% per year.
Step-by-step explanation:
so he has 600 $ saving then if he has 1,200 total in the bank
2y = -1x -8
rewrite each of the following equations in y= mc + b form
Answer: y=-1x-8
Step-by-step explanation:
The first step is to: Move the 'X' to the right side of the equation.
The second step is to: Divide the 'Y'
But since the 'X' is already on the right side you will just divide the 'Y'. If the 'X' was on the left then you will follow those steps that I gave you at the beginning in order to get it in the y=mx+b.
So it will look like this:
2y=-1x-8
y=-1x-8
y= -1(is the slope)x-8(is the Y-intercept)
So, if you have to graph this you will graph it starting with negative 8 as the y-intercept. Then you will go down one and over 1.

the main sailboat has the dimensions shown in figure at the right . what is the height of the main sail? Then round to the nearest tenth as needed.)
Answer:
h = 14.49 feet.
Step-by-step explanation:
From the attached figure,
Base = 14 ft
Height = h
Angle = 46°
We need to find the height of the main sail. To find it we can use trigonometry.
The relation between height, base and angle is given by :
[tex]\tan\theta=\dfrac{\text{Height}}{\text{Base}}\\\\\tan(46)=\dfrac{h}{14}\\\\h=\tan(46)\times 14\\\\h=14.49\ ft[/tex]
So, the height of the main sail is 14.49 feet.

Samantha plays a game in which she rolls two standard dice and finds the sum of the dots facing up. Which shows all the possible outcomes for each roll of the dice?
Answer:
Kindly check attached picture
Step-by-step explanation:
A standard dice has 6 faces numbered {1,2,3,4,5,6}
For 2 dice, n = 2 ; sample space = n² = 6² = 36
The sum of the 2 upward facing dots:
{(1,1) (1,2) (1,3) (1,4) (1,5) (1,6);
(2,1 ) (2,2),(2,3),(2,4),(2,5),(2,6) ;
(3,1)(3,2)(3,3)(3,4)(3,5)(3,6);
(4,1)(4,2)(4,3) (4,4)(4,5)(4,6);
(5,1)(5,2)(5,3)(5,4)(5,5)(5,6);
(6,1)(6,2)(6,3)(6,4)(6,5)(6,6)}
What should be subtracted from -8xy + 2x^2 + 3y^2 to get x^2 + 2
Answer:
x^2 - 8xy + 3y^2 - 2
Step-by-step explanation:
(-8xy + 2x^2 + 3y^2) - unknown = x^2 + 2
- unknown = x^2 + 2 + 8xy - 2x^2 - 3y^2
- unknown = -x^2 + 8xy - 3y^2 + 2
Unknown = x^2 - 8xy + 3y^2 - 2
Check:
(-8xy + 2x^2 + 3y^2) - (x^2 - 8xy + 3y^2 - 2)
= -8xy + 2x^2 + 3y^2 - x^2 + 8xy - 3y^2 + 2
= -8xy + 8xy + 2x^2 - x^2 + 3y^2 - 3y^2 + 2
= x^2 + 2
You're planning on making 7 meatloafs for a party. You go to the store to buy breadcrumbs, and see they are sold by the canister. How many canisters do you need to buy? First, determine what information you need to answer this question, then click here to display that info (along with other info). How much breadcrumbs does the recipe call for?

Paula can spend no more than $500 for a photographer to take specialty photos for the dinner. Aerial photos from a drone cost $25 each, and wide-angle photos costs $50 each. Suppose the photographer takes 11 aerial photos. What is the maximum number of wide-angle photos that Paula can afford?
Answer:
4
Step-by-step explanation:
because 25×11= 275 and 500-275 =225
50x4=200
225-200=25 you can buy 4 and 25$ is left over

please help me . i will help you whenever you want
Answer:
6.7cm
Step-by-step explanation:
We apply Pythagoras Theorem twice.
First we find out the diagonal of the base of the cuboid.
The diagonal of the base = sqrt (2^2+4^2) = sqrt (20).
Then we find out AB by applying Pythagoras Theorem.
AB^2 = 5^2 + [sqrt (20)]^2
AB^2 = 45
AB = 6.7cm (correct to 1 decimal place)

Solve the following system of equations:
y = 2x +1
y=-x+ 4
x=?
y=?
Answer:
x = 1, y = 3
Step-by-step explanation:
Given the 2 equations
y = 2x + 1 → (1)
y = - x + 4 → (2)
Substitute y = 2x + 1 into (2)
2x + 1 = - x + 4 ( add x to both sides )
3x + 1 = 4 ( subtract 1 from both sides )
3x = 3 ( divide both sides by 3 )
x = 1
Substitute x = 1 into (1) and evaluate for y
y = 2(1) + 1 = 2 + 1 = 3
Then solution is x = 1, y = 3
Sherry is driving 390 miles to visit The gateway arch in St. Louis. She drives at an average rate of 65 miles per hour. Explain how you can find the amount of time it will take Sherry to get to the arch
Answer:
t = 6 s
Step-by-step explanation:
Given that,
Sherry is driving 390 miles to visit The gateway arch in St. Louis.
She drives at an average rate of 65 miles per hour.
We need to find the amount of time it will take Sherry to get to the arch. Let the time is t.
Speed = distance/time
[tex]t=\dfrac{d}{v}\\\\t=\dfrac{390}{65}\\\\t=6\ h[/tex]
Hence, it will take 6 hours to get to the arch.
