5.3x - 9 + 7.6x simplify pls
Answer:
12.9x-9
Step-by-step explanation:
add 5.3x and 7.6x
Answer:
12.9x-9
Step-by-step explanation:
First you have to combine the like terms which are 5.3x + 7.6x= 12.9x. Then you just rewrite the equation 12.9x-9. You just leave the 9 by it self because there's no other like terms.
More examples -
5.3x+−9+7.6x
Combine Like Terms:
=5.3x+−9+7.6x
=(5.3x+7.6x)+(−9)
=12.9x+−
What is the total area, in square meters, of the shaded sections of the trapezoid
below?
7 m
9.9 m
10 m
8.6 m
Answer:
84.5m would be the area
Step-by-step explanation:
7m, 10m = 35m
9.9m, 10m= 49.5m
35m + 49.5m+ 84.5m
The circumference of a circle is 17 π π in. Find its diameter, in inches
Answer:
r = 8.5 inches
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
17 pi = 2 * pi *r
Divide each side by 2 pi
17 pi / ( 2pi) = 2 * pi r/ ( 2 pi)
17/2 = r
8.5 = r
The answer is 8.5 inches.

Answer:
B. AC = 22, BC = 22, AB = 44
C. AC = 30, BC = 30, AB = 60
Step-by-step explanation:
B.
[tex] radius \: \overline {OR} \perp chord \: \overline {AB} [/tex] at C. (given)
[tex] \therefore AC = BC[/tex] (perpendicular dropped from the center of the circle to the chord bisects the chord)
[tex] \therefore 2x - 6 = x + 8[/tex]
[tex] \therefore 2x - x= 6 + 8[/tex]
[tex] \therefore x= 14[/tex]
[tex] AC = 2x-6=2(14)-6=28-6= 22[/tex]
[tex] BC= x + 8=14 + 8= 22[/tex]
AB = AC + BC = 22 + 22 = 44
C.
[tex] radius \: \overline {OR} \perp chord \: \overline {AB} [/tex] at C. (given)
[tex] \therefore BC = AC[/tex] (perpendicular dropped from the center of the circle to the chord bisects the chord)
[tex] \therefore 7x-5=4x+10 [/tex]
[tex] \therefore 7x - 4x= 5 + 10[/tex]
[tex] \therefore 3x= 15[/tex]
[tex] \therefore x= \frac{15}{3}[/tex]
[tex] \therefore x= 5[/tex]
[tex] AC = 4x+10=4(5)+10=20+10= 30[/tex]
[tex] BC= 7x - 5=7(5)-5=35-5= 30[/tex]
AB = AC + BC = 30 + 30 = 60

Can someone help me with this?
Answer:
Step-by-step explanation:
We first need to figure out how much money Jackie has since Pilar has the same amount of money, but in different coins. Jackie has 24 dimes and 13 quarters, so the amount of money is $2.40 + $3.25 = $5.65; therefore, Pilar has $5.65 also. In order to determine how many nickels and quarters Pilar has, we have to have a system of equations. It's up to us to write the equations we need to solve this. The first equation has to do with the NUMBER of coins Pilar has, the second has to do with the VALUE of each coin. We know that Pilar has only nickels and quarters and that she has a total of 53 coins. So the NUMBER equation is
n + q = 53
The VALUE equation relates how much each coin is worth to the total amount of money it equals:
.05n + .25q = 5.65.
Go back to the first equation and solve it for either n or q. I solved it for n:
n = 53 - q
Plug this into the second equation in place of n now to get:
.05(53 - q) + .25q = 5.65 and
2.65- .05q + .25q = 5.65 and
.20q = 3 so
q = 15. This means that there are 15 quarters. If there are 15 quarters, then there are
n + 15 = 53 nickels and
n = 38 nickels.
What exactly does it mean when a question says "consecutive integers"?
Answer:
Consecutive integers are those numbers that follow each other. They follow in a sequence or in order. For example, a set of natural numbers are consecutive integers.

[tex]\huge\boxed{(2,\ 3);\ (-1,\ 6)}[/tex]
Step-by-step explanation:
[tex]f(x)=x^2-2x+3\to y=x^2-2x+3\\f(x)=-x+5\to y=-x+5\\\\\left\{\begin{array}{ccc}y=x^2-2x+3&(1)\\y=-x+5&(2)\end{array}\right[/tex]
substitute (1) to (2):
[tex]x^2-2x+3=-x+5[/tex] add x to both sides
[tex]x^2-2x+x+3=-x+x+5[/tex]
[tex]x^2-x+3=5[/tex] subtract 5 from both sides
[tex]x^2-x+3-5=5-5[/tex]
[tex]x^2-x-2=0\\\\x^2+x-2x-2=0\\\\x(x+1)-2(x+1)=0\\\\(x+1)(x-2)=0\iff x+1=0\ \vee\ x-2=0\\\\\boxed{x=-1\ \vee\ x=2}[/tex]
substitute the values of x to (2):
[tex]x=-1\\\\y=-(-1)+5=1+5=6\\\\\huge\boxed{(-1,\ 6)}\\\\x=2\\\\y=-2+5=3\\\\\huge\boxed{(2,\ 3)}[/tex]
make b the subject of the formula a=\sqrt(b+6)
Making 'b' the subject of formula gives b = a² - 6
How to determine the subject of formulaIt is important to note that the subject of formula is described as a variable that is made up to stand alone in an equation.
The subject of formula is the variable that is worked out on on side of the equation sign.
From the information given, we have the equation;
a = [tex]\sqrt{(b + 6)}[/tex]
To make 'b' the subject of formula, we take the following steps;
Find the square of both sides, we get;
a² = [tex](\sqrt{(b + 6)} ^2[/tex]
Cancel out the square, we get;
b + 6 = a²
collect the other terms on one end of the equation, we have;
b = a² - 6
Hence, the equation is b = a² - 6
