The base of an isosceles triangle is 2 cm. The perimeter of the triangle is 10 cm.

cluponka [151]

Answer and Step-by-step explanation:

$Greetings!$

$Let's~solve~your~question!$

$To~find~the~length~of~equal~sides~of~an~isosceles~triangle,~we~use~the~following\\formula.$

$\boxed{~P=2a+b~}$

$Now,~solving~for~``a":$

$P=\frac{P}{2} -\frac{b}{2}$

$=\frac{10}{2}-\frac{2}{2}$

$=5-1$

$=4$

$Thus,~each~equal~sides~of~an~isosceles~triangle~is~4cm.$

$Hope~my~answer~helps~and~have~a~blessed~day~ahead!$

A.6/5 divided by -3/2

Dmitriy789 [7]

A is -12/15 (4/5)
B is 35/12
C is 56
D is 8/15
Sorry if any of these are wrong.
To check them, turn any mixed number into an improper fraction. Then, multiply by the reciprocal. Ex: 4/0 divided by 1/3
X reciprocal- 4/0 times 3/1

Solve the following equation for y: 35x - 7y = 49, what is the slope?

agasfer [191]

Answer:

y = 5x - 7

slope = 5

Step-by-step explanation:

35x - 7y = 49

Subtract 35x from both sides.

-7y = -35x + 49

Divide both sides by -7.

y = 5x - 7

The equation is now in the slope-intercept form, y = mx + b, where m is the slope.

slope = m = 5
