Answer:
This will be the sum of a geometric series where the first term is 4
The common ratio is -5
And we will have 6 terms.....so....the sum is
first term [ 1 - common ratio^number of terms ] / [ 1 - common ratio ] =
4 [1 - (-5)^6] / [ 1 - -5 ] =
4 [ 1 - 15625 ] / 6 =
(2/3) ( -15624 ) =
-10416
Step-by-step explanation:
Answer
a - 6 in each row, 12 altogethor
b - 5 in each row, 15 altogethor
c - 4 in each row, 16 altogethor
d - 2 in each row, 8 altogethor
color each row a diffrent color
Let the number of large chairs be x and small chairs be y
40x + 30y = 26 x 60 = 1,560 . . . . (1)
80x + 75y = 57 x 60 = 3,420 . . . . (2)
(1) x 2 => 80x + 60y = 3,120 . . . . (3)
(2) - (3) => 15y = 300 => y = 300/15 = 20
From (2), 80x + 75(20) = 3,420 => 80x + 1,500 = 3,420 => 80x = 3,420 - 1,500 = 1,920 => x = 1,920/80 = 24
Therefore, the company should produce 24 large chairs and 20 small chairs.
Answer:
C!
Step-by-step explanation:
Solve for
y
y in
2
x
+
y
=
8
2x+y=8.
y
=
8
−
2
x
y=8−2x
2 Substitute
y
=
8
−
2
x
y=8−2x into
4
x
+
6
y
=
24
4x+6y=24.
−

−8x+48=24
3 Solve for
x
x in
−
8
x
+
48
=
24
−8x+48=24.
x
=
3
x=3
4 Substitute
x
=
3
x=3 into
y
=
8
−

x
y=8−2x.
y
=
2
y=2
5 Therefore,
x
=
3
y
=
2
x=3
y=2
look in comments to read it better but x=3 y=2 hope this helps :)
