Answer:
Step-by-step explanation:
5x+9y=-3 Multiply both sides by 8
40x+72y=-24
-53x-8y=-3 Multiply both sides by 9
-477x -72y= -27
sum the equations vertically to eliminate one variable
40x+72y= -24
-477x-72y= -27 (the y cancels out )
-477x =-51 (-24 + -27=-51)
-477x=-51 / -477 divide both sides by -477
x =51/437
5x 51/437=9y= -3 substitute the value of x
y= -174 /437
(x,y) = (51/437, -174/437)
Nine more than the product of a number and 4 is equal to 7.
Answer:
equation is 9+(4x) = 7
x = -0.5
Step-by-step explanation:
+ 9 to (4x) equals 7
9 + 4x = 7
4x = -2
x = -0.5
to prove:
9+(-0.5*4) = 7
9 + -2 = 7
7 = 7
(x - 9)(x - 4)
multiply the binomials

Divide $200 in the ratio 3:2. What is the result?
a. $140 : $60
b. $120 $80
c. $80: $120
d. $300 : $200
Answer:
b) $120 , $ 80
Step-by-step explanation:
Ratio = 3 :2
Total = 3 + 2 = 5
3/5 of 200 = [tex]\frac{3}{5}*200[/tex]
= 3 * 40
= $ 120
2/5 of 200 = [tex]\frac{2}{5}*200[/tex]
= 2 * 40
= $ 80

Fifty less than four times a number is ten. What is this number?
Let the number be x.
The equation is:
4x - 50 = 10
=> 4x = 10 + 50
=> 4x = 60
=> x = 60/4
=> x = 15
So, the number is 15.

Step-by-step explanation:
Perimeter of ΔABC = 12+ perimeter of ΔACD
Perimeter of ΔABC= AC+CB+BA
Perimeter of ΔACD=AC+CD+DA
But, CB=CD +DB
DA ≅DB since there is a ⊥bisector trough D and
Therefore,
Perimeter of ΔABC= (AC+CD+DA)+BA = Perimeter of ΔACD +12 therefore AB=12

You are shopping for a new computer monitor. It is regularly priced at $200 but it is now on sale for 25% off. After the sale discount is applied, you can also use your 20% off coupon. What is the final price?
a. 110
b. 120
c. 130
d. 140
Answer:
b=120
Step-by-step explanation:
Using proportions, it is found that the final price of the new computer monitor is given by:
b. 120
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
It is regularly priced at $200 but it is now on sale for 25% off, hence 75% of $200 is paid, so:
P1 = 0.75 x 200 = 150.
You can also use your 20% off coupon, hence the final price is of 80% of $150, then:
FP = 0.8 x 150 = $120.
Which means that option B is correct.

If the area of a circle is 324 cm, find:
Its circumference in terms of pi
Answer:
20.3π cm
Step-by-step explanation:
Area of a circle = 324 square cm
πr² = 324
[tex]\frac{22}{7}*r^{2}= 324\\\\ r^{2} = \frac{324*7}{22}\\\\ r^{2}= 103.09\\\\ r =\sqrt{103.09}\\\\[/tex]
r = 10.15 cm
Circumference = 2πr
= 2 * π * 10.15
= 20.3π cm

Which equation is equivalent to n + 4 = 11? *
O (n +4 × 2 = 11
(n + 4) x 2 = 1112
(n+ 4) x 2 = 1184
O (n+4) x 2 = 11 * 2

Answer:
(n + 4) *2 = 11 * 2
Step-by-step explanation:
(n + 4) *2 = 11 * 2
Divide both sides by 2
[tex]\frac{(n + 4) *2}{2} = \frac{11 * 2}{2}[/tex]
n + 4 = 11

Question 1 1 The area of a rectangle is 1 2/3 square feet. The width of the rectangle is 5/6 feet. What is the length of the rectangle? o foot D 11. feet 0 2 feet O2 feet Question 2 1 p
Answer:
2ft
Step-by-step explanation:
Given parameters:
Area of the rectangle = [tex]1\frac{2}{3}[/tex]ft²
Width of the rectangle = [tex]\frac{5}{6}[/tex]ft
Unknown:
Length of the rectangle = ?
Solution:
The area of a rectangle is given as:
Area of rectangle = length x breadth
Now insert the parameters and solve for length
[tex]\frac{5}{3}[/tex] = L x [tex]\frac{5}{6}[/tex]
L = [tex]\frac{5}{3}[/tex] x [tex]\frac{6}{5}[/tex] = 2ft
