Mr Akika has 18 21-cent stamp and 31 31-cent stamp.
He has 49 21-cent and 31-cent stamps all told.
let
x = number of 21 cent stamp
y = number of 31 cent stamp
Therefore,
<h3>Total number of stamp:</h3>
<h3>Total cost of stamp:</h3>
Therefore,
x + y = 49
21x + 31y = 1339
21x + 21y = 1029
10y = 310
y = 310 / 10
y = 31
Therefore,
x = 49 - 31
x = 18
Therefore, Mr Akika has 18 21-cent stamp and 31 31-cent stamp.

Answer:
<h2>
b = -2</h2>
Step-by-step explanation:
The point-slope form of equation is: y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope.
m = 2
(4, 6) ⇒ x₀ = 4, y₀ = 6
So, the point-slope form of equation:
y - 6 = 2(x - 4)
Changing to the slope-intercept form of the equation of the line (y = mx + b, where m is the slope and b is the y-intercept of the line):
y - 6 = 2x - 8 {add 6 to both sides}
y = 2x - 2 ⇒ b = -2
Answer:
V = 11.4 cubic yards
Step-by-step explanation:
1 foot = 12 inches
1 yard = 36 inches
1 cubic yard = 46656 cubic inches
change the given values to inches by multiplying by 12
Length = 10'8" , round to higher foot
Length = 11*12 =
Length = 132 inches
Width = 6'4", round to higher foot
Width = 7*12
Width = 84 inches
Depth = 4'
Depth = 4*12 = 48 inches
The volume V = length x width x depth = 132 x 84 x 48 = 532224 cubic inches
divide by 46656 get cubic yards
V = 11.4 cubic yards
Answer:
y=4/3x+1
Step-by-step explanation:
So basically you have to do the same thing you would do without the perpendicular part. Then just filp the 3/4x to 4/3 and solve for b.
Hope this helps :)
The answer is 6.2(A) Turn the mixed numbers into improper fractions b multiplying the whole number by the denominator. Do this for both fractions then multiply normally.<span />
