StartFraction x + 3 over 19.99 EndFraction + StartFraction y + 4 over 14.99 EndFraction StartFraction 3 x over 19.99 EndFraction + StartFraction 4 y over 14.99 EndFraction 19.99 (x + 3) + 14.99 (y + 4) (3 x) 19.99 + (4 y) 14.99
Answer:
19.99(x+3)+ 14.99(y+4)Step-by-step explanation:
Step one:
given data
day one
x shirts that cost $19.99 each and
y pairs of shorts that cost $14.99 each.
Day two
3 more shirts that cost $19.99 each and
4 more pairs of shorts cost $14.99 each.
Step two:
the total number of shirts is
x+3
and the total number of shorts is
y+4
The total cost is ex[ressed as

t÷5/12= -3/10
Thank you if you help :)
Answer:
t = -1/8.
Step-by-step explanation:
t / 5/12 = -3/10 Invert the 5/12 and multiply:
12t / 5 = -3/10
Cross multiply:
12t * 10 = 5 * -3
120t = -15
t = -15/120 = -1/8.
A bottle of water contains 450ml. How many litres of water are there in 8 of these bottles
Answer:
3.6 litres
Step-by-step explanation:
1 bottle = 450ml
8 bottles = 450 × 8
= 3600ml
1000ml = 1 litre
3600ml = 3.6 litres (3600÷1000)
Answer:
3.6 litres
Step-by-step explanation:
1 bottle = 450ml
8 bottles = 450 × 8
= 3600ml
1000ml = 1 litre
3600ml = 3.6 litres (3600÷1000)

If the measure of angle 1 is (3 x minus 4) degrees and the measure of angle 2 is (4 x + 10) degrees, what is the measure of angle 2 in degrees?
A horizontal line. A line extends from the line to form a 90 degree angle. Another line cuts through the 2 lines to form angles 1 and 2, which total 90 degrees.
32 degrees
38 degrees
58 degrees
66 degrees
Answer:
58 degrees
Step-by-step explanation:
3x-4+4x+10=90
7x+6=90
7x=84
x=12
4(12)+10=angle 2
58 degrees = angle 2
Answer:
C. 58 Degrees

A person has a rectangular board 12 inches by 16 inches around what she wants to put a uniform border of shells if she hasn't of shells were border whose area is 128 square in determine the width of the Border
Answer:
2 inches
Step-by-step explanation:
Given that:
Dimensions of rectangular board = 12 inches by 16 inches
Area of uniform border around the rectangular board = 128 square inches
To find:
Width of the border = ?
Solution:
Let the width of the uniform border = [tex]x[/tex] inches
Now, there are two rectangular shapes after the addition of border.
One rectangle with the border, one without the board.
Area of border can be found by subtracting the area of board from the area of rectangle with the board.
Dimensions of the rectangle with the border = (12+2[tex]x[/tex]) inches by (16+2[tex]x[/tex]) inches
Area of rectangle = Length [tex]\times[/tex] Width
So, area of border = ((12+2[tex]x[/tex]) [tex]\times[/tex] (16+2[tex]x[/tex])) - 16 [tex]\times[/tex] 12 = 128 square inches
[tex]\Rightarrow 4x^2+56x+192-192=128\\\Rightarrow 4x^2+56x-128=0\\\Rightarrow x^2+14x-32=0\\\Rightarrow (x+16)(x-2)=0\\\Rightarrow x = 2, -16[/tex]
Width can not be negative, so possible value of width = 2 inches

In Triangle JKL, ∠J is congruent to ∠L. Triangle J K L is shown. Ray L K extends beyond point K to form an exterior angle that is labeled sixty-seven and eight tenths degrees. What is the measure of ∠L? Enter the correct answer in the box.
Answer:
m<L = [tex]33.9^{o}[/tex]
Step-by-step explanation:
Triangle JKL is an isosceles triangle, given that <J ≅ <L. An isosceles triangle has two of its angles and sides to be equal.
The exterior angle formed = [tex]67.8^{0}[/tex]
But,
<J + <L = [tex]67.8^{0}[/tex] (the sum of two opposite interior angles is equal to the exterior angle)
Let <J ≅ <L be represented by a, so that;
a + a = [tex]67.8^{0}[/tex]
2a = [tex]67.8^{0}[/tex]
a = [tex]\frac{67.8^{o} }{2}[/tex]
= [tex]33.9^{o}[/tex]
The measure of <L is m<L = [tex]33.9^{o}[/tex] (m<L =
Thus,
m<J ≅ m<L = [tex]33.9^{o}[/tex]
