Answer:

c. Side-Angle-Side

Step-by-step explanation:

Two sides (AB and AC) and an included angle (<BAC) in triangle ∆ABC are congruent to two corresponding sides (AD and AC) and an included corresponding angle (<DAC) in ∆ADC.

Therefore, by the SAS Congruence Theorem, both triangles are congruent.

Which of these strategies would eliminate a variable in the system of equations? \begin{cases} 6x + 5y = 1 \\\\ 6x - 5y = 7 \end

IRISSAK [1]

Answer:

x = 0.667 and y = -0.6

Step-by-step explanation:

Given that,

6x + 5y = 1 ....(1)

6x - 5y = 7 ...(2)

We need to solve the above equations.

Subtract equations (1) and (2)

6x + 5y -(6x - 5y) = 1-7

6x+5y-6x+5y = -6

10y=-6

y = -0.6

Put the value of y in equation (1).

6x + 5(-0.6) = 1

6x = 1-5(-0.6)

6x = 4

x = 0.667

Hence, first step is to subtract equation (1) and (2) then put the value of y in equation (1).

Please help me idk this

Stells [14]

We are given that Donna knit a total of 12 blankets.

She took 4 months in doing it.

To find the number of blankets in 1 month, take ratio of number of blankets to number of months.

$\frac{number \: of \: blnkets}{number \: of \: months} \\ \\ = \frac{12 \: blankets}{4 \: months} \\ \\ = \frac{3 \: blankets}{1 \: months}$

Thus, she knit 3 blankets in 1 months
