Solve the system -0.18x + y = -6.54 -2.8x - y = -2.4

1 answer:

5 0

ADDING THE 2 EQUATIONS TO ELIMINATE Y WE HAVE

-2.98x = -8.94
x = 3

Plug x=3 into first equation:-
-0.18(3) + y = -6.54
y = -6.54 +0.54 = -6

answer x= 3 and y= -6.

Pls help I dont know how to do this

german

Answer:

1. CE = 63
2. x = 16

Step-by-step explanation:

Use proportions to solve.

Corresponding sides have same ratio.

Question 1

DE/EG = CE/EF

(6x + 3)/17 = (8x - 1)/21
21(6x + 3) = 17(8x - 1)
126x + 63 = 136x - 17
10x = 80
x = 8

CE = 8*8 - 1
CE = 63

Question 2

KM/MD = KZ/ZH

(x + 8)/21 = 32/28
x + 8 = 21*8/7
x + 8 = 24
x = 24 - 8
x = 16

Please help me solve

mihalych1998 [28]

Answer:

x = 36.3°

using tane rule:

$\sf tan(x)= \dfrac{opposite}{adjacent}$

Here!

x = missing angle

opposite = 22

adjacent = 30

=============

$\hookrightarrow \sf tan(x) = \dfrac{22}{30}$

$\hookrightarrow \sf x= tan^{-1}(\dfrac{22}{30} )$

$\hookrightarrow \sf x= 36.253^{\circ \:}$

$\hookrightarrow \sf x= 36.3^{\circ \:}$ ( rounded to nearest tenth of a degree)
